6.7 is released now, some distros are already shipping it!
This commit:
1. adds a new 6.7 requirements file (the plain 6 one has already been
updated by the bot)
2. adds a new tox env referring to the new requirements file
3. updates the mac and windows installer jobs to run with pyqt67 with the
assumption we'll be including that in our next release
4. adds two new CI environments for 6.7, one each for python 3.11 and 3.12
(3.12 only came out like 6 months ago)
5. updates a couple of references to the py37 tox env that looked like they
were missed, 3.7 support was dropped in 93c7fdd
6. updates various ubuntu containers to the latest LTS instead of the previous
related one - this is quite unrelated to this change but I thought I would
give it a go, no need to use the old one unless we are specifically testing
on it?
- linters - they use tox but probably use system libraries
- these all run in nested containers anyway, should be fully isolated
- codeql - eh, uses a third party action, check the docs if it fails
- irc - as above
