Add recommendation to packages

Problem

Actually aren't great way for recommendation some packages in other packages. Now can package publisher use only:

• collections (actually the best but in the first package you can't see, what is in package and now are collections relatively hidden)
• optional_depends (it is for technical depends but not for thematic recommendation)
• write it in README and mod page (not good visible for downloaders)
• write it on forum/discord (nobody see it)

Do you think that your mod will be great with some game although is technically usable in more other games? Do you think that for your mod is great using texturpack from other creator? Or did you make two technically not-depends mods but for decoration is nice, when somebody want one from them, use both?

Solutions

Add category (as is depends and optional_depens) named "recommended_with" or similar - for thematic recommendation.

Alternatives

Big rework of colletions but I think that it will be so much harder to work and not so beneficial as category "recommended_with".

Additional context

I think that this doesn't need picture.

No files or tests are named. Begin by locating the package metadata handling for collections, depends, and optional_depends, then determine where a recommended_with category would be exposed to downloaders. Done means publishers can declare thematic recommendations and users can see them clearly.
