Securely install the latest uv release from PyPI.

This action installs a pinned version of uv and all its dependencies, making sure that file hashes match. Pinning your dependencies:

1. Stops software supply chain attacks.
2. Makes sure your CI does not break unexpectedly.

In your GitHub Actions workflow, use this action like so:

      - name: Install uv from PyPI
        uses: install-pinned/uv@1286654590b8e8d3e2e45916552bbd11761f4c52  # 0.5.7

You can set up Dependabot so that your pins are updated regularly.

This action is a relatively simple wrapper around uv and is most useful if there is no existing requirements.txt/uv.lock/... infrastructure in place. If you already pin all your dependencies in a single place, you don't need it!

See the @install-pinned README for details.
