refactor(api): allow deleting reserved attestation/bundle fields

Ignore the `FIELD_NO_DELETE` breaking-change rule for
`workflow_run.proto`. The deprecated `attestation` and `bundle` fields
are removed in this change; their tag numbers and names are reserved in
the proto to prevent accidental reuse.
