Use an empty vendored file system in Ruff

[MichaReiser]

Summary

This PR changes removes the typeshed stubs from the vendored file system shipped with ruff
and instead ships an empty "typeshed".

Making the typeshed files optional required extracting the typshed files into a new ruff_vendored crate. I do like this even if all our builds always include typeshed because it means red_knot_python_semantic contains less code that needs compiling.

This also allows us to use deflate because the compression algorithm doesn't matter for an archive containing a single, empty file.

Test Plan

cargo test

I verified with cargo tree -f "{p} {f}" -p <package> that:

• red_knot_wasm: enables deflate compression
• red_knot: enables zstd compression
• ruff: uses stored

I'm not quiet sure how to build the binary that maturin builds but comparing the release artifact size with strip = true shows a 1.5MB size reduction

@charliermarsh this is a potential short term fix for the conda forge build

I'm happy to release it today if you want

[MichaReiser]

Nice. Could you try running the new analyze method over a real project? Just to make sure we don't show annoying warnings when the versions file is empty 😆

[MichaReiser]

But yeah. Feel free to merge and release the changes to unblock conda forge.

For changelog: Fix conda forge build.

I love your confidence 😆

This file shouldn't be here

[MichaReiser]

Thanks. I don't understand why it sometimes creates those files but doesn't delete them when the test is done.

[charliermarsh]

Just ran, no warnings :)
