[Feature] Popups

[BurkusCat]

Is your feature request related to a problem? Please describe.
When using the MVVM library, it feels completely different to show a popup compared with navigating to another page or a modal. Perhaps an existing popup library could be integrating into the Burkus Mvvm NavigationService. This would make usage of a popup library more testable too.

Describe the solution you'd like
A new NuGet package that integrates with one or both of the below libraries:
https://learn.microsoft.com/en-us/dotnet/communitytoolkit/maui/views/popup
CommunityToolkit/Maui#1165
https://github.com/LuckyDucko/Mopups
(any other options?)

Describe alternatives you've considered
N/A

Proposed APIs
Unsure

Additional context
If it takes a dependency on another library, perhaps it should be a separate NuGet package.
