fix: stop a failed step disabling the toolkit patch (#1177)

Browse Source 
A step that failed, for any reason, made the runner restore the action's stock bundle and mark it never to be patched again. Every later `actions/upload-artifact` run then failed with `GHESNotSupportedError`, and nothing in the log said why.

The edit is now made as the action is copied into the job container, under the lock that guards the copy, and nothing reverts it. That also closes the race where another job's checkout reset the bundle mid-job.

`cache.v2` no longer decides whether the edit is made, it only withdraws the v2 advertisement, so artifacts work whatever the cache is set to.

Also added a new `runner.patch_actions` option to turn the edit off if it ever breaks an action.
