[Therion] Upgrade to Fedora 37 - Problems with proj packages

[Bill Gee]

I think this is not really a Therion problem, but it is likely to affect 
Therion users who run Fedora.  The recent release of Fedora 37 does not 
have the proj package that Therion requires.  Attempting an upgrade 
gives this:

Error:
  Problem: package therion-6.1.2-1.fc36.x86_64 requires 
libproj.so.22()(64bit), but none of the providers can be installed
   - proj-8.2.1-6.fc36.x86_64 does not belong to a distupgrade repository
   - problem with installed package therion-6.1.2-1.fc36.x86_64
