patch	minor

Expose the catalog-import route as an external route from the scaffolder.

This will make it possible to hide the "Register Existing Component" button when you for example are running backstage with catalog.readonly=true.

As a consequence of this change you need add a new binding to your createApp call to keep the button visible. However, if you instead want to hide the button you can safely ignore the following example.

To bind the external route from the catalog-import plugin to the scaffolder template index page, make sure you have the appropriate imports and add the following to the createApp call:

import { catalogImportPlugin } from '@backstage/plugin-catalog-import';

const app = createApp({
  // ...
  bindRoutes({ bind }) {
    // ...
    bind(scaffolderPlugin.externalRoutes, {
      registerComponent: catalogImportPlugin.routes.importPage,
    });
  },
});
