[Bug] cref to generic types renders type incoorrectly

**Describe the bug**

Hete is the documentation I have:

```csharp
///
/// Provides a set of static methods for creating instances of type.
///
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` 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`
