Unify release pipelines for related packages

We should mirror what we've done for data plane language repos so we can release updated packages together and avoid versioning mismatches (i.e., the ability to release all Foundry packages or just some subset).

Start by reviewing the existing release approach for data plane language repositories and identifying how Foundry packages are currently versioned and released. Done means related packages can be released together, either as all Foundry packages or as a selected subset, without versioning mismatches.
