[Python] Format generated files using ruff

[dbrattli]

Use Ruff formatter on the generated Python output files. This makes the generated files easier to read and also makes it easier to spot any issues with the generated code. Ruff format is Black compatible but super fast so it doesn't really add much to the total compile time.

@MangelMaxime Any ideas about this? I'm not familiar with the new build system, so perhaps there's something obvious I'm doing wrong? Works locally btw on my mac. https://github.com/fable-compiler/Fable/actions/runs/6703457876/job/18214036253?pr=3578#step:6:52

@dbrattli It seems like the CI is fixed now.

For me the problem seems to be that you were trying to run poetry before it was installed on the CI.

And you also tried to invoke it from inside the temp/fable-libary-py/library_py folder when the tool is installed at the root of the repository.

One question that I have is do we still need to have fable-library reference in the top level pyproject?

Fable/pyproject.toml

Lines 15 to 16 in 5d309a0

	[tool.poetry.dev-dependencies]
	fable-library = {path = "./temp/fable-library-py", develop = true}

Because of that line, I had to not restore the poetry dependencies directly in the CI commands but only after fable-library-py has been built otherwise the path is missing.

@MangelMaxime Aha, I see, thanks a lot for fixing!!

No problem, happy to help on what I can. :)
