Enable ScrollViewer Chaining in the Sample App?

### Describe the bug

See guidance on [scroll chaining here](https://learn.microsoft.com/en-us/windows/apps/design/input/guidelines-for-panning#:~:text=concept%20of%20rails.-,chaining%20embedded%20or%20nested%20content,-After%20a%20user)

Basically, we want to be able to continue to scroll down a page, and if a sample is using a scroll viewer to continue past that sample once it's finished scrolling as well.

Problem is this is probably not supported by the OS? 😟 See:

> Because mouse wheel rotations are handled as inertial manipulations, chaining does not work.

From: https://learn.microsoft.com/en-us/uwp/api/windows.ui.xaml.controls.scrollviewer.isverticalscrollchainingenabled

Not clear if it'd be resolved by https://github.com/microsoft/microsoft-ui-xaml/issues/108

Also see https://github.com/microsoft/microsoft-ui-xaml/issues/7902

### Steps to reproduce

```text
1. Open Sample App
2. Look at a sample that involves scrolling (like the Header Behaviors from https://github.com/CommunityToolkit/Windows/pull/136)
3. Try scrolling down the page (i.e. with a mouse wheel)
4. You get halted at the bottom of any of the lists from scrolling.
```

### Expected behavior

Can continue to scroll.

### Additional context

Maybe this is something we need to investigate a helper for for now?
