fix: nested drawer onOpenChange issue

[chrism]

This appears to fix the open issue
Nested drawer doesn't fire onOpenChange callback #457

And also allows for the nested drawer to be controlled independently via nestedIsOpen

I noticed that the onOpenChange got removed in this commit
v0.9.2...v0.9.4#diff-0b5adbfe7b36e4ae2f479291e20152e33e940f7f265162d77f40f6bdb5da7405L1071

For my use case I also needed to open a nested drawer on route change, I've attached a short video to illustrate what I mean.

vaul.mp4

For info: to ensure that the parent drawer transitions correctly when the nested drawer is opened on route change I also needed to add this code

  React.useEffect(() => {
    setTimeout(() => {
      onNestedOpenChange(!!nestedIsOpen);
    }, TRANSITIONS.DURATION * 1000 + 50);
  }, [nestedIsOpen]);

Maybe there is a cleaner way, but it seems to work.

Thought this fix might be useful to others.
