User Story: As Author I would like to be able to link content type to rich text content via dialog  so that I can access all contentApp resources without unnecessary steps.

As developer I would like to have a possibility to easily configure "link contentType"  plugin so that I can easily activate plugin in rich text editor, I should be able to easily configure workspaces/applications available via dialog.

Description:

Similarily to the native magnolia plugins: "link to page" or "link asset" we need to introduce new link type configurable by developers - steps by would like to achieve from author perspective are:
1. Click on plugin link

2. Dialog opens with configured apps

3. After selecting App/workspace dialog jump to second step with the content of selected app

4. after selecting item and clicking choose - link is assigned to the content in rich text editor.

Acceptance Criteria:

• The plugin must be easily configurable by developers using Magnolia standard patterns - If we will use any "external config file" then needs to be clearly described how such configuration works so that we can include this in docu.

• The plugin allows authors to link to various content types within the rich text editor.

• A user-friendly dialog should open upon interacting with the plugin, displaying the configured applications or workspaces.

• After selecting an app/workspace, the dialog should display the relevant content for further selection.

• The chosen item should seamlessly integrate as a link in the rich text editor.
