Bump python version

[dklimpel]

Python 3.7 is EOL

Python 3.11 is also the Python version of Synapse in Dockerfile

Max Python version here: 3.10.
The upgrade to Python 3.11 seems to need more dependency updates.

      gcc -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -fPIC -Iast27/Include -I/home/runner/work/sygnal/sygnal/.tox/check_codestyle/include -I/opt/hostedtoolcache/Python/3.11.4/x64/include/python3.11 -c ast27/Custom/typed_ast.c -o build/temp.linux-x86_64-cpython-311/ast27/Custom/typed_ast.o
      In file included from ast27/Custom/typed_ast.c:3:
      ast27/Custom/../Include/compile.h:5:10: fatal error: code.h: No such file or directory

            |          ^~~~~~~~
      compilation terminated.

Possible solutions / causes:

• https://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg1878635.html
• Pre-commit fails to run when typed_ast needs to be built. pre-commit/pre-commit#2850 (comment)

Related to:

• Upgrade dependencies #342

Reason / Solution:

• Cannot import name "Feature" from "setuptools" in version 46.0.0 pypa/setuptools#2017

Thanks!

I'm pretty sure this broke apns configurations, as we pinned back aioapns to an older version that didn't support Python 3.10 here: #293
