Adds citus version into matrix

[gurkanindibay]

Currently, our support matrix does not include Citus versions. When I add Citus version, I needed to parametrise tox testing framework scripts. However, I can not execute docker-compose to execute in tox framework. Additionally after adding additional django versions, test durations reached to nearly 15 minutes. Therefore, I removed tox and execute all tests under GitHub Actions To run the tests in various python environments, I needed a docker image, which includes all the required python versions To keep the image up-to-date, I added a pipeline to bake this image as well Now, we have full-fledged understandable and extendable test environment

Another note, looks like this PR is related to https://github.com/citusdata/django-multitenant/pull/132 which you previously approved. Are we able to close that one now in favor of this one?

One little thing then good to go

Edit: can you also double check whether the instructions in CONTRIBUTING.md are still up to date? It talks about how to run tests and format the code.

Yes it's up-to-date
