Subject: [PATCH 1/2] fix(bazel): take into account `MODULE.bazel.lock` for
 cache invalidation

This change now considers also `MODULE.bazel.lock` as part of the cache key.

Also, we which an issue where we had an invalid path in the cache key `\%LocalAppData\%`. These paths are not expanded. See: https://github.com/actions/cache?tab=readme-ov-file#windows-environment-variables

Subject: [PATCH 2/2] fix(github-actions): replace `C:\` to `/mnt/c`

Since Bazel will run in WSL under Windows we need to update the `--repository_cache` to use the WSL mounted path.
