test(docker): add AlmaLinux 9 image

[scop]

Mostly for Bash 5.1 test coverage, and likely eventual CentOS 7 replacement.

[scop]

CI doesn't currently handle adding new images properly, so I'm seeding ghcr.io/scop/bash-completion/test:almalinux9 by pushing my locally built image.

[scop]

Quite a few errors/failures in the first run. Messy notes from my local run that I have not sorted through.

$ docker run --rm -t -v $PWD:/usr/src/bash-completion -w /usr/src/bash-completion ghcr.io/scop/bash-completion/test:almalinux9 test/docker/entrypoint.sh

[scop]

Can't seem to reproduce any of those failures in a plain interactive run, like

docker run --rm -it -v $PWD:/usr/src/bash-completion -w /usr/src/bash-completion ghcr.io/scop/bash-completion/test:almalinux9 bash
pytest test/t/test_python3.py
# etc

[scop]

Seems the tests are flaky, getting random different errors across runs with plain

pytest --verbose -p no:cacheprovider --numprocesses=auto --dist=loadfile test

in an interactive container.

Tried also running the orignal tests without --numprocesses=auto --dist=loadfile in entrypoint.sh, but doing so yields the same errors.

[scop]

Ok, two classes of problems here:

• parallel tests are flaky, getting rid of --numprocesses=auto --dist=loadfile serves as a workaround (CI already does this)
• our current problems with load dir precedence is the culprit for the rest -- a rpm -e bash-completion hack in the test/docker/entrypoint.sh and then running on almalinux9 avoids all the remaining issues seen here

So in that sense I consider this PR to be actually mergeable as is.
