Overall project health improvements

[giovannicimolin]

Hey folks,

There's a number of improvements and fixes we need to do to get this repository in a good shape again. For now, our focus is to get new builds out to Pypi, but that is (hopefully) about to get finished.

With that, we need to start working on a few things that will help the overall health of the project and maintainability moving forward.

Here are a few things I want to do with this repository before the end of the year:

• [ ] Add a changelog management tool (as suggested by @johnraz here: https://github.com/jazzband/django-rest-knox/pull/342#issuecomment-2097717682)
• [ ] Update developer documentation and readme
• [ ] Add more code samples to the example application and link it on the documentation
• [ ] Increase test coverage
• [ ] Simplify and document the development and release flow

Any other suggestions? Feel free to add them here! Do you want to pick up any items above? Create an issue and ping me there. :rocket:
