I think we should do snap points using inertia modifiers as described here: https://learn.microsoft.com/en-us/windows/uwp/composition/inertia-modifiers

I looked into it. Looks like we need to use https://learn.microsoft.com/en-us/windows/windows-app-sdk/api/winrt/microsoft.ui.composition.interactions.interactiontracker.configurepositionxinertiamodifiers?view=windows-app-sdk-1.6#microsoft-ui-composition-interactions-interactiontracker-configurepositionxinertiamodifiers(windows-foundation-collections-iiterable((microsoft-ui-composition-interactions-interactiontrackerinertiamodifier)))

It's not straight forward to implement.

Closing this PR for now and can pick this up later.
