Add github-discussions workspace at commit backstage/community-plugins@c44f724 for backstage 1.32.1 on branch release-1.4.

This PR was created automatically.
You might need to complete it with additional dynamic plugin export information, like:

• the associated app-config.dynamic.yaml file for frontend plugins,
• optionally the scalprum-config.json file for frontend plugins,
• optionally some overlay source files for backend or frontend plugins.

Before merging, you need to export the workspace dynamic plugins as OCI images,
and 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.
