Fixes #30265 1. Read second type of dependencies 2. Render `Description` and `ReleaseNotes` old:  new:  The NuGet spec does not specify what kind of text can be stored in the description but we can best guess markdown. The official NuGet registry just [converts the newlines to html lines](https://www.nuget.org/packages/rb.Firefox#readme-body-tab). 3. Extract and render the readme. This is the new and better place to store larger text than in the description. The content is markdown.  --------- Co-authored-by: Benjamin Heemann <benjamin.heemann@raith.de>
