Purpose

• Dependabot is dying because python-test.yaml is using an old version of postgresql (that has been retired) which Django utils can't use any more
• GitHub Actions was brownouting to highlight the need to bump the Ubuntu version from 20.04 to 24.04, the latest LTS
• This fixes both issues, and allows Dependabot to do its thing
