Support uv tool install on Windows

[henryiii]

On windows, uv tool install gives the warning:

warning: `C:\Users\runneradmin\.local\bin` is not on your PATH. To use installed tools, run `$env:PATH = "C:`\Users`\runneradmin`\.local`\bin;$env:PATH"`.

And then you can't use what it installs.

I think setup-uv should add ~/.local/bin to the path if it's not there and/or on Windows. For a composite action, it would be something like this:

- if: runner.os == "Windows"
  shell: bash
  run: echo "$USERPROFILE/.local/bin" >> $GITHUB_PATH

That's the workaround I'm using in scientific-python/cookie#493.

Agreed, good call.

I think https://github.com/moonrepo/setup-rust does this.

Thank you.

I am testing a solution in #87 where the UV_TOOL_BIN_DIR env var is used to place tools on the much faster D: drive. This is then automatically added to the PATH

Is that drive documented by GitHub? I'm unable to find information about it.
