Feature: add drag feature to Wolt Modal Bottom Sheet

[AcarFurkan]

Description

Scroll feature added to Wolt Modal Bottom sheet. enableDrag has been updated to enableCloseDrag. Now, when enableDrag is true, the position and size of the bottom sheet can change according to the user's wishes. enableDrag and enableCloseDrag can be used together or separately.
(I could not add these changes to the dynamic property page because there was a bug #205 in the operation of dynamic properties. That's why I assigned enableDrag to true in the home example so that you can test it.)

Let's revisit this one later. We have improved the modal drag a lot since this PR has been opened.

Any plans to add this feature? It's very helpful @ulusoyca

Yes, in the future it is possible. Current focus is allowing full customization for modals, and introduce Wolt defaults with 0.7.0. This can be investigated with persisten sheet epic.
