Update acs workspace at commit backstage/community-plugins@d27bb85 for backstage 1.40.2 on branch main.

This PR was created automatically.

⚠️ Manual re-approval required
An override exists at workspaces/acs/backstage.json. This upgrade is a Best-Effort match.
Since the previous version was manually verified to work against the target Backstage version, please review and test again before merging.
The overridden backstage.json has been removed because it's out-of-sync (1.39.1) with the Backstage version of the new source commit (1.40.2).
A new one should be added after testing the plugins against the target Backstage version.
Don't forget to also update the repo-backstage-version field in source.json accordingly.

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.

Publish workflow has completed with failure.

@sachaudh The publish failure above comes from the fact that the plugin sources are built against Backstage 1.40.2, which is not by default known to be compatible with Backstage 1.42.5:

https://github.com/redhat-developer/rhdh-plugin-export-overlays/actions/runs/18472945662#summary-52630986613

However you can easily use the PR-specific container image published above to test this plugin inside RHDH next.

Known Backstage compatibility can then be overridden in this overlay repository.
