Subject: [PATCH] ci: fail PRs when generated maps are out of date (#3876)

## Description:

## Summary
- Adds a `gen-maps` job to the CI workflow that runs `npm run gen-maps`
(Go map generator + prettier) and fails the check if the working tree
has any diff afterwards.
- The failure annotation tells the author to run `npm run gen-maps`
locally and commit the result, so stale generated maps can't slip
through review.
- Pulls the Go toolchain version from `map-generator/go.mod` so the CI
version stays in sync with the module automatically.


## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced

## Please put your Discord username so you can be contacted if a bug or
regression is found:
