Why do you remove wasdk target when both "uwp, wasdk" are specified in `GenerateAllSolution.ps1`?

### Describe the bug

I just wasted several hours trying to figure out why is my wasdk gallery project suddenly missing in the main toolkit project. And I finally found [this out](https://github.com/CommunityToolkit/Tooling-Windows-Submodule/blob/9f2cd6730a313e47fca61e53728d8c9f88cd8dad/GenerateAllSolution.ps1#L65). I don't understand what this comment is saying. And from my experience, the two gallery (the uwp, and wasdk) works perfectly in peace before.

And if that's a necessary change, you should [document it](https://github.com/CommunityToolkit/Windows/wiki/Quick-Start#building-the-entire-solution) clearly (and oh look even the screenshots is not reflecting the change), and also change the [`GenerateAllSolution.bat`](https://github.com/CommunityToolkit/Windows/blob/906519524a9dc61118f4f65fb727a3031ecf3ebf/GenerateAllSolution.bat#L3) to an option like:
- uwp, wasm
- wasdk, wasm

The current default value is just a confusing contradiction to what you did, and will keep others wasting more hours on this.

Oh and a more funny thing is, why removing `wasdk` target instead of `uwp` when `uwp` is considered dead?
