Switching to Hatch for package management

[benoit-cty]

I suggest to use Hatch because it will provide a better dependencies management for CodeCarbon.

It also a way to move from setup.py to more modern pyproject.toml

It will also replace tox, venv, and make.

It will simplify the management of the project. For example to run the dashboard locally you just have to do :

hatch run dashboard:run

And Hatch will handle the installation of the needed Python version, the creation of the environment and the package dependencies.

All the requirements are defined id pyproject.toml and a lock is generated for different part of the project in a requirements folder.

TODO:

• [x] Update contributing
• [x] Update readme
• [x] Update documentation
• [X] Migrate CI to use Hatch instead of Tox
• [x] Remove tox
• [x] Remove setup.py

-As I have to modify the config of checks, no other PR could be merge before rebasing on this one !-

NO : I put back Matrix test in Github Actions to allow them running in parallel.
