Error installing `@backstage/plugin-circleci` dependency

I'm trying to migrate to this package from `@backstage/plugin-circleci`. When I run `yarn --cwd packages/app add @circleci/backstage-plugin` I get this error:
```
% yarn --cwd packages/app add @circleci/backstage-plugin

Am I doing something wrong?

Reproduce the reported command from packages/app with Yarn 4.4.1, using the error output as the starting point. Inspect the workspace configuration and package metadata related to the missing @backstage/catalog-model workspace reference. Done means the dependency installs successfully or the issue documents the required migration steps.
