Build: modernization of build process

[mrava87]

This PR modernizes the build process of pyproximal by:

• switching from setuptool to hatchling`
• changing the deploy.yaml file to use Trusted Publisher Management (no more secrets.PYPI_API_TOKEN), and make an overall update based on Update deploy.yaml GitHub Action #242

@cako I think this is the final step to modernize our tooling 😄 would appreciate if you can have a look and let me know if you agree. Only once I do a release I will see if it works (but having added test-pypi on tags should give me the opportunity to test it once before I go for an official release).

Once this goes through I'll start repeating all the steps in PyLops
