EPIC Goal

Investigate which strings are not translated yet in the Backstage Catalog plugin and it's dependencies. (catalog, catalog-react, catalog-graph) and add "translation support" (call t()) for these.

Why is this important?

Customers want have a fully localizated RHDH.

Backstage core plugins needs to support localization so that we can add translations in RHDH.

To archive this in 1.9 we need to have these work done before Backstage 1.45 gots released.

Acceptance Criteria

1. All Backstage Catalog strings that are visible by default should be "translatable" (Other languages will be added somewhere else). This includes
   1. The list / table pages for Catalog, API, Documentation – Filter and table columns
   2. Catalog details pages – About card with all the labels like Name, description, etc.
   3. Catalog graph views (catalog-graph plugin)
2. Please check the code for components that are just shown for specific entity kinds or types.

This work could be splitted into different PRs if this makes sense.
