[Modal] Expose onScrolledToBottom on Modal from it's Scrollable implementation

[posth]

Modal

If using Scrollable as the Modal's content, it's onScrolledToBottom handler won't get triggered.

The Modal component implements it's own Scrollable here

Maybe exposing that implementation's handler as a new prop on Modal may enable consumers of Modal to play around with infinite scrolling, for example.

Examples

Here is an example that uses Scrollable with a handler wrapped within the Modal. The Scrollable handler does not get called when reaching the bottom.

The issue seems to be related to the content within Scrollable being dynamically generated, because here is an example that has fixed content where the behavior is as expected.

Here is an example of Scrollable on its own triggering the handler.

This makes sense to me. It'll prevent nesting Scrollable which may be weird UI issues. I think it'll be a great addition 😄
