As discussed in astral-sh/uv#9326 currently

- name: Install uv
  uses: astral-sh/setup-uv@v3
  with:
    cache-local-path: ~/.uv_cache

does not expand the ~ to /home/username and instead results in a '~' folder being created in the working directory.

Instead it would be nice if the ~ was expanded for this path as well as the other path inputs tool-dir and tool-bin-dir.

• Support $HOME in Path Argument actions/upload-artifact#8 (comment)
• Home directory cannot be accessed via ~ softprops/action-gh-release#368 (comment)
