Update packaging to use modern packaging with a pyproject.toml

[terencehonles]

This change updates and modernizes the packaging to use hatchling as that is used in the main RQ project.

This fixes deprecation warnings that pip is starting to produce:

DEPRECATION: Building 'django-rq' using the legacy setup.py bdist_wheel mechanism, which will be removed in a future version. pip 25.3 will enforce this behaviour change. A possible replacement is to use the standardized build interface by setting the --use-pep517 option, (possibly combined with --no-build-isolation), or adding a pyproject.toml file to the source tree of 'django-rq'. Discussion can be found at pypa/pip#6334

fixes: #553

I built the wheels and sources before and after this change and they look good.

Do you want to update this?

Hey @terencehonles thanks for this. Just wanted to check whether this will also fix #716 (comment)

It looks like #716 is an issue of when the release was cut. Looking at setup.py at the v3.0.1 tag it does indeed not provide the extra, and looking at the commit history 4ccb412 is only on master and not part of any release.

So this provides the same extras as that commit does, but really just a new release will fix the issue reported in #716

Thanks!
