Revert "Update README.md with mdbook-pandoc install" (#1998)
Reverts google/comprehensive-rust#1975

Using `mdbook-pandoc` requires more than just installing the `mdbook`
plugin: it requires

- A whole LaTeX installation
- A Pandoc installation
- Some fonts

This is essentially why the output is configured as optional in
`book.toml`: the assumption is that people won't have `mdbook-pandoc`
installed without the necessary supporting tools.

@henrif75, I assume you added this because you didn't like the warning
`mdbook build` prints:

```
% mdbook build
2024-04-16 10:45:56 [WARN] (mdbook::book): The output.html.curly-quotes field has been renamed to output.html.smart-punctuation.
Use the new name in book.toml to remove this warning.
2024-04-16 10:45:56 [INFO] (mdbook::book): Book building has started
2024-04-16 10:45:57 [INFO] (mdbook::book): Running the exerciser backend
2024-04-16 10:45:57 [INFO] (mdbook::renderer): Invoking the "exerciser" renderer
2024-04-16 10:45:57 [INFO] (mdbook::book): Running the html backend
2024-04-16 10:45:58 [INFO] (mdbook::book): Running the pandoc backend
2024-04-16 10:45:58 [INFO] (mdbook::renderer): Invoking the "pandoc" renderer
2024-04-16 10:45:58 [WARN] (mdbook::renderer): The command `mdbook-pandoc` for backend `pandoc` was not found, but was marked as optional.
```

I don't have the necessary dependencies on my local system and this is
what I get after installing `mdbook-pandoc`:

```
2024-04-16 10:47:30 [INFO] (mdbook::renderer): Invoking the "pandoc" renderer
Unable to run `pandoc -v`: No such file or directory (os error 2)
2024-04-16 10:47:30 [ERROR] (mdbook::renderer): Renderer exited with non-zero return code.
2024-04-16 10:47:30 [ERROR] (mdbook::utils): Error: Rendering failed
2024-04-16 10:47:30 [ERROR] (mdbook::utils): 	Caused By: The "pandoc" renderer failed
```

This also means that `mdbook serve` doesn't work unless all dependencies
are installed.

As an alternative, we could remove the `output.pandoc` settings from the
`book.toml` file and use a small shell script to add them when needed.

We actually have the same problem for the `mdbook-xgettext` output
format which generates the POT files: we only want to run this
occasionally. This is currently done by overriding `output` from the
command line using the `MDBOOK_OUTPUT` environment variable:

```shell
MDBOOK_OUTPUT='{"xgettext": {"pot-file": "messages.pot", "granularity": 0}}' \
  mdbook build -d po
```

It's a bit ugly and it results in people missing/forgetting some of the
configuration options we want them to use (the `granularity` setting).
So I would like to move this configuration to the `book.toml` file — but
I'm reluctant since I don't think we need to generate POT files on every
build (it takes ~1 second and would slow down `mdbook serve`).

Cc @max-heller in case you have ideas here.

# Comprehensive Rust 🦀

This repository has the source code for Comprehensive Rust 🦀, a multi-day Rust
course developed by the Android team. The course covers all aspects of Rust,
from basic syntax to generics and error handling. It also includes deep dives on
[Android], [Chromium], [bare-metal], and [concurrency].
[Android]: https://google.github.io/comprehensive-rust/android.html
[Chromium]: https://google.github.io/comprehensive-rust/chromium.html
[bare-metal]: https://google.github.io/comprehensive-rust/bare-metal.html
[concurrency]: https://google.github.io/comprehensive-rust/concurrency.html
Read the course at **https://google.github.io/comprehensive-rust/**.
## Course Format and Target Audience
The course is used internally at Google when teaching Rust to experienced
software engineers. They typically have a background in C++ or Java.
The course is taught in a classroom setting and we hope it will be useful for
others who want to teach Rust to their team. The course will be less useful for
self-study since you miss out on the discussions happening in the classroom. You
don't see the questions and answers and you don't see the compiler errors we
trigger when going through the code samples. We hope to improve on this via
[speaker notes](https://github.com/google/comprehensive-rust/issues/53) and by
[publishing videos](https://github.com/google/comprehensive-rust/issues/52).

## Building
The course is built using a few tools:
- [mdbook](https://github.com/rust-lang/mdBook)
- [mdbook-svgbob](https://github.com/boozook/mdbook-svgbob)
- [mdbook-i18n-helpers](https://github.com/google/mdbook-i18n-helpers)
- [mdbook-exerciser](mdbook-exerciser/)
- [mdbook-course](mdbook-course/)
First install Rust by following the instructions on https://rustup.rs/. Then
clone this repository:
```shell
git clone https://github.com/google/comprehensive-rust/
cd comprehensive-rust
```
Then install these tools with:
```shell
cargo install mdbook
cargo install --locked mdbook-svgbob
cargo install --locked mdbook-i18n-helpers
cargo install --locked --path mdbook-exerciser
cargo install --locked --path mdbook-course
```
Run
```shell
mdbook test
```
to test all included Rust snippets. Run
```shell
mdbook serve
```
to start a web server with the course. You'll find the content on
<http://localhost:3000>. You can use `mdbook build` to create a static version
of the course in the `book/` directory. Note that you have to separately build
and zip exercises and add them to `book/html`. To build any of the translated
versions of the course, run `MDBOOK_BOOK__LANGUAGE=xx mdbook build -d book/xx`
where `xx` is the ISO 639 language code (e.g. `da` for the Danish translation).
[TRANSLATIONS.md](TRANSLATIONS.md) contains further instructions.
> **Note** On Windows, you need to enable symlinks
> (`git config --global core.symlinks true`) and Developer Mode.
