API Browser redirecting to .net Framework 4.8.1 or earlier for a lot of APIs

What the title says.

The API Browser, when told to go to .net 10 or 11, is redirecting to .net Framework 4.8.1 or earlier. This makes a lot of APIs unreachable.

May be happening for other frameworks as well. I did not test it beyond trying 3 different browsers and a handful of namespaces, all for .net 10 and 11.

Many namespaces seem to be affected.

Here are a few:
* [System](https://learn.microsoft.com/en-us/dotnet/api/system?view=net-10.0) - Goes to .net Framework 4.8.1
* [System.Buffers](https://learn.microsoft.com/en-us/dotnet/api/system.buffers?view=net-10.0) - Goes to netstandard 2.1
* [System.Buffers.Binary](https://learn.microsoft.com/en-us/dotnet/api/system.buffers.binary?view=net-10.0) - Goes to netstandard 2.1
* [System.Collections.Generic](https://learn.microsoft.com/en-us/dotnet/api/system.collections.generic?view=net-10.0) - Goes to .net framework 4.8.1, making things like [PriorityQueue](https://learn.microsoft.com/en-us/dotnet/api/system.collections.generic.priorityqueue-2?view=net-10.0) unreachable via the tree (I built the link myself)

Many more were broken, too.
Tested in Firefox, Edge, and Chrome.
