Freeze Break Request: update fedora-repos-zchunk on composers

The new fedora-repo-zdicts-2309.1-1.fc38 update has f39 zchunk dictionaries, which should make the zchunk deltas better for f39. I'd like to update compose-branched01/compose-rawhide01/compose-x86_01 so we can get this advantage. I think this is a pretty low impact change and we can always just back out to the older version if something happens. +1s? kevin
