Replace setup.py with pyproject.toml and other metadata changes

[je-cook]

Description

Closes #3669

This changes the install to use a pyproject.toml. Some things to consider when reviewing:

• This now uses hatch(ling) to replace setuptools with hatch-vcs to create the version dynamically based off the git tag
• Ive moved all the requirements into the pyproject and slightly rearranded them, probably could be done better
• All the ruff config is now in the file
• All the data is included via the artefacts bit
• The pyproject was copied and modified from one of my other packages so may need some small cleanup

Adding some support for the pyproject way of doing things: the current version number in setup.py does not match the version number for the latest release (3.2.2):

PROCESS/setup.py

Line 15 in 2cd900d

"version": "3.2.1",

This change would mean not having to remember to update the number in the future.

I have a few suggestions about which dependencies should be installed in the testing jobs. I think part of our tests job is to check we have our dependencies sorted out hence we should be strict with which dependencies are installed in these jobs--other jobs dont matter so much.

Some new issues should be created from this:

• Transform our CI to use hatch (will solve the Python version element of Matrix unit tests with Python version and OS #3848)
• Enable more ruff rules and fix any issues

May I recommend https://github.com/Fusion-Power-Plant-Framework/fppf-actions or modifications to it to unite our CI
