Re-enable org wide PR bot (#195131)

#194768 without the merge

Switches over to the org wide PR bot, with backwards compatibility for
both versions.

Updating the pipeline definition here is a global set for environment
variables on all branches, so I intend on merging the backports first to
support both versions and then proceeding with this.
