action based on branch protection settings:
required_linear_history, required_approving_review_count and
require_code_owner_reviews.
Add commits condition.
Add commits-behind condition.
Add linear-history condition.
The option users_from_teams has been added to request_reviews
action.
Allow to specify timezone in current-time, schedule,
created-at, merged-at, closed-at and updated_at conditions.
Pull requests that change the content of the .github/worflows
directory are now supported by backport, copy, merge and
queue actions.
