Update `python_interpreter` to 3.11

[austlane]

Upgrades AWX-EE from Python 3.9 to Python 3.11. Bringing with it 3.11's speed improvements. https://docs.python.org/3/whatsnew/3.11.html

This also replaces python-unversioned-command with alternatives command -- as python-unversioned-command always links to python3.9 in EL9

Working in my local testing:

% ansible-builder create -v3 --context context --output-filename Dockerfile
% docker buildx build -f context/Dockerfile -t awx-ee:dev-py311 context --platform linux/amd64
% docker run -it --user=root awx-ee:dev-py311 bash

ansible [core 2.15.0]

  configured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']

The roadmap for Ansible 2.16 seems to indicate this interpreter upgrade will be necessary soon. See:

• https://github.com/ansible/ansible/pull/80973
• https://github.com/ansible-collections/news-for-maintainers/issues/49

https://docs.ansible.com/ansible/devel//roadmap/ROADMAP_2_16.html#planned-work

- Drop Python 3.9 support for controller

Ansible-core 2.16 is out already, so would be great to get this is merged.

We've been running with the patch from the PR in our custom EEs for a while and it works fine. The only issue is for localhost tasks we need to specify the correct python interpreter, which was quickly resolved by setting ansible_python_interpreter: /usr/bin/python3.11 in inventory.yml.

Any update ? We have a different problem with python 3.9, ansible 8.7.0 and above all ansible-core 2.15.7

Any update about this one?
