ci(stlc): route promote/sync workflows to the renamed staging repos

The staging repos were renamed openlayer-<lang>-staging-new → openlayer-<lang>-staging
(legacy mirrors moved to -staging-old). Update the `github.repository ==` gates and
STAGING_REPO accordingly so promote, back-sync and seal-dispatch keep running.
