The shared plugin-release.yaml reusable workflow declares pull-requests: write
and uses it to create/merge the release PR. Calling workflows must grant all
permissions declared by reusable workflows or the job fails at startup.
Also adds secrets: inherit so org-level RELEASE_APP_ID and RELEASE_APP_PRIVATE_KEY
are forwarded to the external reusable workflow — without this they arrive empty
and the release is silently skipped.
