V14/feature/custom generic swagger

[Migaroez]

Prerequisites

• I have added steps to test this contribution in the description below

Description

Some of the generic names in the swagger docs are excessively long without giving useful meaning.

Requirements / todo

• Come up with a maintainable, typed implementation
• Doublecheck implementation matches purpose
• Check whether more models require this treatment
• Verify performance/magic strings usage
• OpenApi spec has been updated

Reporoduction

Open management api swagger: /umbraco/swagger/index.html?urls.primaryName=Umbraco%20Management%20API
Verify ContentTypeResponseModelBaseDocumentTypePropertyTypeResponseModelDocumentTypePropertyTypeContainerResponseModel is now ContentTypeForDocumentTypeResponseModel

Before merging

• Check with frontend

We will need to update the OpenApi.json file, but I like the idea of an attribute.

Obviously we need to coordinate with frontend when to merge
