[dependabot]

Bumps actions/download-artifact from 3 to 4.

Release notes

Sourced from actions/download-artifact's releases.

v4.0.0

What's Changed

The release of upload-artifact@v4 and download-artifact@v4 are major changes to the backend architecture of Artifacts. They have numerous performance and behavioral improvements.

ℹ️ However, this is a major update that includes breaking changes. Artifacts created with versions v3 and below are not compatible with the v4 actions. Uploads and downloads must use the same major actions versions. There are also key differences from previous versions that may require updates to your workflows.

For more information, please see:

1. The changelog post.
2. The README.
3. The migration documentation.
4. As well as the underlying npm package, @​actions/artifact documentation.
