[AIRFLOW-XXXX] Used fixed periodic auto-labeler from potiuk's repo (#…

…7047)

The periodic labeler had a bug that it was not using pagination.
In effect the labeler was checking only 30 oldest request and
if they all contained proper labels, it was not checking any more
PRs.

Details are available in
paulfantom/periodic-labeler#4

But until it is merged, we switch to our own fixed version.
