Promote translation refs from alpha to stable entry points

Add each plugin and package translation ref to the corresponding stable
entry point, changing the JSDoc tag from @alpha to @public. The alpha
entry points now re-export with a @deprecated annotation so existing
consumers continue to work.

Affected packages: core-components, api-docs, catalog, catalog-graph,
catalog-import, catalog-react, home, home-react, kubernetes,
kubernetes-cluster, kubernetes-react, notifications, org, scaffolder,
scaffolder-react, search, search-react, user-settings.
