build: use the create-pr-for-changes action from angular/dev-infra (angular#47410)

Use the `create-pr-for-changes` action of the `angular/dev-infra` repo,
instead of the `gkalpak/dev-infra` one. The latter was used during
development for debugging purposes during and was accidentally committed
to the repo.
