Subject: [PATCH 2/2] qa: add ci

Does Continuous Integration using GH actions using:

1. Bionic / Python 3.6 / gcc 7 - because that's used in the
   dogecoin/dogecoin CI
2. Focal / Python 3.8 / gcc 9 - because that's the stable old-lts
3. Jammy / Python 3.10 / gcc 11 - because that's the current lts
4. Jammy / Python 3.10 / clang 14 - to also test clang

all on x86_64
