Add git history link to the Archives policy

Commit 8e7e52101ccee added links to the git history for policies, but
missed to include the archives policy in this. Fix by adding the link.

Daniel tried to do this in commit dfb58ef8, reverted in 3293b0ef because
he missed the "load pgfilters" part. So add that part and un-revert the
rest to actually add it this time.
