## Summary

<!-- What's the purpose of the change? What does it do, and why? -->

Since the [`junction` crate](https://crates.io/crates/junction)
implements Windows-only functionality, and since the only place it is
used is guarded by `#[cfg(windows)]`,


https://github.com/astral-sh/uv/blob/1f626bfc7300a700257348e1890af90837c740e6/crates/uv-fs/src/lib.rs#L65-L86

it makes sense not to depend on this crate at all on non-Windows
platforms.

If nothing else, this makes Linux distribution packagers’ lives just a
*tiny* bit easier.

## Test Plan

<!-- How was it tested? -->

On Fedora Linux 39:

```
# To avoid an error when /tmp and the working directory are on different filesystems:
$ mkdir _tmp
$ TMPDIR="${PWD}/tmp" cargo run -p uv-dev -- fetch-python
$ cargo test
```

I don’t have access to a Windows system.
