Use Ruff on generated code (can replace isort)

https://beta.ruff.rs

Config example:
```toml
# pyproject.toml

[tool.ruff]
# https://beta.ruff.rs/docs/rules
line-length = 88 # Default
select = ["ALL"]
ignore = [
# "D203",
# "D213",
"D",
"RUF009", # See `extend-immutable-calls`
"ERA001", # Detects comments as code
# "A003", # See `builtins-ignorelist`
"UP006", # https://github.com/danielgtaylor/python-betterproto/issues/485
]

[tool.ruff.flake8-builtins]
builtins-ignorelist = ["id", "type"]

[tool.ruff.flake8-bugbear]
# https://github.com/charliermarsh/ruff/issues/4355
extend-immutable-calls = ["betterproto.*"]
```

It's possible to have it only emulate isort, but I've tried to enable as much as possible from it, which is still incredibly fast.

Can be run as `ruff check --fix`.

Commencez par localiser la configuration de formatage du code généré et toute configuration existante d'isort, puis consultez la documentation de Ruff liée dans l'issue. Exécutez `ruff check --fix` sur le code généré et vérifiez que Ruff fournit les contrôles attendus tout en remplaçant l'utilisation actuelle d'isort ; l'exemple de configuration de l'issue montre la direction attendue.
