Before merging, you need to export the workspace dynamic plugins as OCI images,
and if possible test them inside a RHDH instance.

To do so, you can use the /publish instruction in a PR review comment.
This will start a PR check workflow to:

• export the workspace plugins as dynamic plugins,
• publish them as OCI images
• push the oci-images in the GitHub container registry with a PR-specific tag.
