Do we need license headers for YAML files? We've never done so before.

We never have; other teams do do so however: https://github.com/googleapis/google-cloud-rust/blob/main/generator/dart/pubspec.yaml. I'll see if there are any related docs (or @itsjustkevin, if you have any relevant links, can you share?).

Will reach out to the compliance office for more information, this is also requesting the addition of a header to a generated file.
