Description: I installed electrum for the first time, went to start it, and it fails due to qt version issues.

## Steps to reproduce:

Try to start electrum. It seems to have been built against an older version of qt than what arch is currently on. I cloned the git repo and built manually, but still get the same error. I'm not sure what this implies: something else "baked in" to electrum is looking for qt? Or one of the dependent python libs is?

$ electrum
Cannot mix incompatible Qt library (5.15.2) with this library (5.15.3)
Aborted (core dumped)
