Update formatting tooling

[Wauplin]

Related to transformers's PR (see related internal discussion)

This updates the quality tools for 2023. Mainly:

• use black 23
• replace isort and flake8 by ruff, which is faster and merges imports contrarily to isort
• change default line length to 119 instead of 88
• make the update in Makefile, pre-commit and CI

Basically: align with transformers's settings. Goal is to get a consistent coding experience for contributors.

@sgugger I listed the few changes compared to transformers config.

• add .ruff_cache/ to .gitignore => cache folder that is generated by ruff
• removed isort from the dependencies => I don't think it's useful anymore (at least for hfh as it's all done by ruff)
• completely removed flake8 and isort configuration (except [tool.ruff.isort]) => same here. Haven't seen any different with or without those configs (since we removed flake8/isort from makefile)

Bonus: here is the vscode settings that I now use.

  "[python]": {
    "editor.formatOnSave": true,
    "editor.codeActionsOnSave": {
      "source.fixAll": true,
    },
  },
  "ruff.fixAll": true,
  "ruff.path": ["(...)/path/to/ruff"], // to complete
  "editor.rulers": [119],

The documentation is not available anymore as the PR was closed or merged.
