Bump to rules_scala-6.5.0, update repo name patch (#322)

Details:

- https://github.com/bazelbuild/rules_scala/releases/tag/v6.5.0

Removes the part of the patch that worked around the removal of
`to_proto` and `to_json` members from a struct, since this version
contains a fix:

- bazel-contrib/rules_scala#1554

Updates the remaining part of the patch to define
`_unmangle_bzlmod_repo_name`. This is in anticipation of the Bazel
maintainers replacing `~` as the canonical repo name format delimiter
due to build performance issues on Windows:

- bazelbuild/bazel#22865

I plan to see about contributing this function to
bazelbuild/bazel-skylib eventually.
