Allow actions to postpone saving the modified entity

Action module is approved for removal. See 🌱 [Policy] Deprecate Action (UI) module in D10 and move to contrib in D11 Fixed

This is now Postponed. The status is set according to two policies. The Remove a core extension and move it to a contributed project → and the Extensions approved for removal → policies.

It will be moved to the contributed Action project when the Drupal 11 branch is open.

I was on 'autopilot' and the above comment is wrong. It is the Action UI that is being removed. Restoring status.

Sorry for the noise.

the module moved to contrib project
