Retire Fedora 31 for 32

We have Fedora 32 nodes now, retire the Fedora 31 testing and replace
with 32.

Docker isn't supported on Fedora 32.  There's a problem with cgroups
v2 and you can read all about it at [1].  Drop the install test.

Haskell upstream has dropped F32 from the COPR repo as it is now
packaged; a new package with the correct dependencies has been pushed
but isn't available yet (see the inline github issue), so workaround
the missing package.
