Refactor JSON fixtures to a scripted logic

[benjaoming]

Details

Currently, we maintain fixtures here: https://github.com/readthedocs/readthedocs.org/blob/main/readthedocs/projects/fixtures/test_data.json

Since it's not clear that the intention/coupling of these fixtures are for either

1. Test cases
2. Demoing / manual tests

...we should probably refactor this to a separate script or test fixture decorator:

Suggestion by @humitos for a quick solution:

#9319 (comment)

Note from @stsewd that current fixtures are included in tests:

#8914 (comment)

Expected Result

Better developer experience maintaining fixtures, better or more fixtures, better test cases

Actual Result

No bugs related to this

Hi @benjaoming I would like to work on this. Continuing from #8914 . However I would need some guidance.
Thanks!

@tanvimoharir

That sounds great!

Expanding on comment from @humitos, I would propose the following adjustments:

• Write a management command for the projects application and call it fixtures_projects
• Make it a tiny bit robust, i.e. use get_or_create or check that the project isn't already created when loading
• Maintain fixtures as a dictionary directly in fixtures_projects.py, do not factor into a separate data file (JSON/YAML etc) unless the need actually arises.
• Call call_command from setUp where test case previously used fixtures.
• Update docker-compose entrypoint web.sh, replacing loaddata with a call to the new management command

(I'll keep updating the above list as other team members may have inputs)
