Rename new Deployment Name and Build ID labels to be shorter

[carlydf]

What changed?

Change temporal_worker_deployment_name -> worker_deployment_name and temporal_worker_deployment_build_id -> worker_build_id.

Why?

Found out that External Obs can add the prefix later, as it does for other tags.
Also dropped _deployment_ from the build id tag because the build id has a stronger relation to the worker than the worker deployment, and this is easier to say and type.

How did you test it?

• built
• run locally and tested manually
• covered by existing tests
• added new unit test(s)
• added new functional test(s)

Potential risks

Zero risk. We added these labels last night. If we can patch this into OSS (or just merge to main and restart Long Haul) no one will ever see the tags we merged last night.

Note

Low Risk
Low risk change limited to renaming two metrics tag keys; the main impact is dashboards/alerts or external tooling expecting the old tag names.

Overview
Renames the metrics tag keys for worker deployment identifiers in common/metrics/tags.go, changing temporal_worker_deployment_name to worker_deployment_name and temporal_worker_deployment_build_id to worker_build_id for shorter labels.
