[Feature Request] Handle duplicate parameter comments better

Currently for this code:
```cs
///
/// Get by ID.
///
/// The ID.
public int GetById(string id)
{
throw null!;
}

///
///
/// Whether the ID is case sensitive.
public int GetById(string id, bool ignoreCase)
{
throw null!;
}
```
the warning `Duplicate parameter 'id' found in comments, the latter one is ignored.` is reported by docfx. The empty `` in the latter method is there to prevent the [CS1573](https://learn.microsoft.com/en-us/dotnet/csharp/misc/cs1573?f1url=%3FappId%3Droslyn%26k%3Dk(CS1573)) warning from being reported while keeping the inherited xml doc from the former method. I think it would be nice if docfx handled such a case and ignored empty xml docs so that this warning isn't reported.
