[red-knot] Typeshed patching: use build.rs instead of workflow (#15370) ## Summary The symlink-approach in the typeshed-sync workflow caused some problems on Windows, even though it seemed to work fine in CI: https://github.com/astral-sh/ruff/pull/15138#issuecomment-2578642129 Here, we rely on `build.rs` to patch typeshed instead, which allows us to get rid of the modifications in the workflow (thank you @MichaReiser for the idea). ## Test Plan - Made sure that changes to `knot_extensions.pyi` result in a recompile of `red_knot_vendored`.
