Add tests files in MANIFEST

[jcapiitao]

Those files are required for distribution packaging, as we need to run the tests during the package build.

Thanks @jcapiitao!
A potential issue here is that someone installing the source package will end up with a tests module at the top level of their site-packages. Do we need to perhaps consider moving this into a submodule of django_libsass (and then potentially adjusting the config so that django_libsass.tests is included in the source package but not the wheel)?

[jcapiitao]

Oh right, we need to move core content and tests into django_libsass directory.
We can also include tests only in sdist and not wheel, do you want me to work on that in this PR ? or should I open new one ?

[gasman]

Yes please - having those updates as part of this PR makes most sense, I think.

[jcapiitao]

With latest commit, we have tests/ folder in source distribution but not the wheel. And top level is django_libsass with just the content in __init__.py.

ls -l .venv/lib/python3.12/site-packages/django_libsass
