This uses the `rustfmt` from the stable toolchain, instead of nightly.
At the moment, nightly's `rustfmt` is nonfunctional, but in general we
don't need bleeding-edge formatting (and in fact, the more often
formatting changes, the more often we'll get spurious failures on PRs,
as we are today).
Fixes#2165.
The type returned by `String::from_utf8(raw)`, is `Result<_>` and needs
to be mapped to match the type of the return type of `next`. You get
this error otherwise:

Updating `fa.po` translations based on the latest changes. If we merge
this before the #2038, it's easier to review that merge request.
Related to #671.

Undefined behavior does not just mean that the behavior can be different
on different platforms. It is much worse than that: the runtime behavior
can be completely nonsensical since the whole program has undefined
behavior.
The compiler will optimizer as if there is no undefined behavior and
will can lead to strange situations as the compiler concludes that
things like `a > a + 1000` can never be reached if `a` is a signed 8-bit
value (since reaching it would trigger undefined behavior).

I've been thinking it'd be simpler to introduce `dyn Trait` via `&dyn
Trait` rather than waiting for the smart pointers section and `Box<dyn
Trait>`. This PR adds a slide to the Generics section that introduces
`&dyn Trait` and compares it to `&impl Trait`, juxtaposing
monomorphization and static dispatch against type-erasure and dynamic
dispatch. I've then updated the existing trait object slide to call back
to the earlier introduction, and call out that using `Box<dyn Trait>`
gives you an owned trait object rather than a borrowed one.
Add a note to the `Copy` slide noting that shared references are `Copy`.
A student asked about this today, and it's something I want to remember
to mention in future classes.
The English contents has changed, leading to untranslated session
outline and schedule because the msgid no longer match the original
contents. Additionally, incorrect file names are listed in the comment.
This PR follow the steps outlined in [Refreshing an Existing
Translation](https://github.com/google/comprehensive-rust/blob/main/TRANSLATIONS.md#refreshing-an-existing-translation)
to refresh the Vietnamese translation file. After the update, some
translated session outlines were no longer appropriated, so this PR also
updates all of them
#1476 issue. Updated the function call(`getCodeFromPlayground`) in
`save-playground.js` file from `pagehide` event to change event in ace
editor.

The example of returning a reference to a local variable doesn't compile
due to a missing lifetime specifier, which isn't what we're trying to
demonstrate with that example. I usually add the lifetime in manually in
order to demonstrate the compiler error, but it occurs to me that if we
make the argument a reference we can sneakily get the correct compiler
error without having to introduce the lifetime syntax.
