https://github.com/bazel-contrib/.github/blob/646899086d7aaee8e532540480f3e91e00596234/.github/workflows/release_ruleset.yaml#L2 for instance is referring to a .yaml file, hence the link is broken. The quick fix would be to fix the comment, however all other files in https://github.com/bazel-contrib/rules-template/tree/main/.github/workflows use .yaml. For consistency, it makes more sense to rename the file in this template, but I am not sure if this could cause any issues further down the road.
