v6.4.0 🌈 Add input `version-file`

Changes

You can now use the version-file input to specify a file that contains the version of uv to install.
This can either be a pyproject.toml or uv.toml file which defines a required-version or
uv defined as a dependency in pyproject.toml or requirements.txt.

- name: Install uv based on the version defined in requirements.txt
  uses: astral-sh/setup-uv@v6
  with:
    version-file: "requirements.txt"
