fix: Use go mod download (#1345)
Recommend using `go mod download` rather than `go mod tidy` for fetching
dependencies. The `tidy` function is used to update things and chagnes
the dependency graph. Using the `download` function avoids any changes.

Some builds may need pre-build steps before building, e.g. `go generate`.
The `before` section allows for global hooks which will be executed before
the build is started.
The configuration is very simple, here is a complete example:
```yml
# .goreleaser.yml
before:
# Templates for the commands to be ran.
hooks:
- make clean
- go generate ./...
- go mod download
- touch {{ .Env.FILE_TO_TOUCH }}
```
If any of the hooks fails the build process is aborted.
It is important to note that you can't have "complex" commands, like
`bash -c "echo foo bar"` or `foo | bar` or anything like that. If you need
to do things that are more complex than just calling a command with some
attributes, wrap it in a shell script or into your `Makefile`.
