mirror: add Fedora 36

Add released Fedora 36 to the mirror.  Traditionally we have kept two
releases (prior and current) around; but depending on what is broken
often we drop the prior release earlier if it is not worth fixing;
this is what happened with F34.  Ergo this is adding 36 and leaving
35, for now.
