@carlossanlop PTAL. What's the process for infra changes in servicing branches?

[carlossanlop]

@sbomer changes that are infra-only and/or test-only can get the servicing-approved label applied automatically, and no need for Tactics approval. Just needs review from area owners. The full process is documented here for future reference: https://github.com/dotnet/runtime/blob/main/docs/project/library-servicing.md
