Some NuGet package enhancements (#30280) (#30324)

Backport #30280 by @KN4CK3R Fixes #30265 1. Read second type of dependencies 2. Render `Description` and `ReleaseNotes` old: ![grafik](https://github.com/go-gitea/gitea/assets/1666336/abac057c-11cd-4d25-b196-01ff899d948e) new: ![grafik](https://github.com/go-gitea/gitea/assets/1666336/35302273-740c-481a-a031-1f80d2d7d336) 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. ![grafik](https://github.com/go-gitea/gitea/assets/1666336/f442264e-3735-4b55-92c4-3b89a8ebafb0) Co-authored-by: KN4CK3R <admin@oldschoolhack.me> Co-authored-by: Benjamin Heemann <benjamin.heemann@raith.de>
