Subject: [PATCH] [CI] Label PRs if polkadot companion build fails (#6410)

* add polkadot-companion-labels.yml

* fix polkadot companion job name

* add opened event to polkadot-companion-labels.yml

* Dont label on timeouts

* increase timeouts

* increase timeouts again... to be sure

* Switch to s3krit/await-status-action

Turns out Sibz/await-status-action looks at /ref/statuses, which lists ALL statuses (i.e., if you send a pending and a failure for the same context, it will see both and assume the job is still pending.). I forked and point at /ref/status, which shows a combined summary of each status (i.e., only ever shows the most recent status of a single context).
