Project overhaul with recent dependencies & code quality

[QuentiumYT]

Hello, here is the PR I propose to maintain this project and keep a code convention using ruff. It also includes numerous improvements & bug fixes around the project.

I recommend reviewing commit by commit to understand exactly what I did, because I formatted the code initially with ruff with defaut settings to have a classic code convention.

GitHub Actions were also updated to provide recent releases and features.

Python standard types & format imports were used instead of old typing library (because Python >= 3.10 support this typing (Python 3.9 added that))

Did some linting with ruff and a few other personal improvements

Dependencies in the uv.lock file are bumped to latest, it has been tested with unit tests

.python-version is not forced, allowing the project to embrace Python 3.14 development if needed (that's what I've did)

Added a package.json for easier dependencies management (complementary to fix CVE)

Removed trailing spaces in LICENSE

Huge rework of docs-site for latest npm versions, latest next and fumadocs. It also fix the missing icon that was initially wanted

Prevent hydration warnings of p tags with recent NextJS (text in div tags are already converted to p tags)

Prevent tag issues with non leading v in create release workflow (see here for example)

Last question remains, is package.json & package-lock.json needed in the root directory?
