[wiki] Remove old patched openIDConnect, and comment about new setup
    
    We previously moved the FPCA check from a patched file held here in
    ansible into the RPM itself when it was built for the Fedora infra
    repos. While we no longer installed the patched file, it remained here
    in the files dir of the wiki role, so we are deleting it.
    
    Also, have added a comment to the play to say where we are holding this
    patch now, so when i forget about it again, and come back to it in
    another year or so, i can remember faster
