generate-doc: don't mention internal interfaces

[benjamin-hodgson]

internal interface IInternal
{
}

public class Public : IInternal
{
}

Running generate-doc on this code produces output markdown that looks like this:

# Public Class

IInternal isn't accessible to consumers and so should not be mentioned in the "Implements" section or in the code snippet showing the declaration. This appears to affect both the github and docusaurus outputs.

Hi,

Thanks for the suggestion. Original idea behind the docs generation was to more or less mimic official .net docs (https://learn.microsoft.com/en-us/dotnet/api/?view=net-9.0). Is your suggestion based on how it's done there? Could you provide some example from .net docs?

For example: ImmutableList implements the internal interface IStrongEnumerable, but that interface does not appear in the docs for ImmutableList.
