The change had to be amended to apply it on main. Specifically, the repo archive_overrides in MODULE.bazel for gz deps were removed in that PR on the Jetty branch, but we want to preserve it on main to ensure CI uses gz deps from HEAD.

-- Original PR description
Few small fixes in MODULE.bazel as pre-work to add automation to push new releases to BCR.

• Drop repo_name, which removes the need to patch MODULE.bazel when pushing a release to BCR. repo_name is not a required field and can be added on the client side during import if needed to disambiguate packages.
• Add compatibility_level to match what is set in BCR
• Add buildifier linting for consistent bazel files formatting.
• Use cc_library and cc_test from rules_cc, rather than native rules which are deprecated in bazel 9. The buildifier lint target added above already enforces this.
• Add module docstring for bazel/gz_rendering_engine_libraries.bzl (enforced by buildifier linting).
• Bump rules_cc and rules_gazebo to versions indicated by bazel in the resolved build graph.
