[Bug]: It's not possible to remove/get query parameters in UriBuilder

[bjarkihall]

Describe the issue

It was already reported in the other repo, where the suggestion was to create a PR:
microsoft/ALAppExtensions#16460

So I did: #2247
But I think the validation needs a ticket within the same repository, so I'm creating this one. I hope this is the right approach, out of the issue templates, a Bug seemed to be the most fitting since I couldn't find a Microsoft idea and this had already been accepted in the other repo.

Expected behavior

UriBuilder should be able to Get/Add/Replace/Remove the queryparameter flags/parameters, but currently it can only Add/Replace them.

Steps to reproduce

Add parameter to UriBuilder instance.
The only way to remove the parameter is to Initialize it again with the Uri from scratch and make sure you don't add the parameter again.

Additional context

No response

I will provide a fix for a bug
