[Bug] cref to generic types renders type incoorrectly

[AlexeyRaga]

Describe the bug

Hete is the documentation I have:

/// <summary>
/// Provides a set of static methods for creating instances of <see cref="Either{_,_}"/> type.
/// </summary>
public static class Either

and here is how it renders by docfx:

Expected behavior

I expect the type name to be rendered correctly and to be a link to EIther<TLeft, TRight> type, as an IDE would show:

Or at least the type name, not "EP.Prelude.Either`2" which doesn't make much sense for documentation readers.

Context (please complete the following information):

• OS: MacOS
• Docfx version: 2.77.0+bd00e2b93951e9e7fa6e5abd990d2cd77d7a83bd

Oh, I think I've found the problem.
I used to have "outputFormat": "apiPage" for my metadata and it didn't work.

Re-open this for tracking. We should also fix the apiPage output in this case.
