[V4] Support DidAttemptToDismiss for pageSheet modals

[manicantic]

Hi, since 4.0.3 there is possibility to set swipeToDismiss under modal options. This is really nice addition, but also implementing DidAttemptToDismiss with a callback would be a great addition to this functionality.
I tried myself to implement this but I am not so good at objective C. But this might helped, in RNNModalManager.m there should be implementation of - (void)presentationControllerDidAttemptToDismiss:(UIPresentationController *)presentationController with getting calling callback passed to options -> modal -> onDismissAttempt or some other property name.

Hi @manicantic,

Sounds like a great feature request!
Will tag @yogevbd and @guyca so they can hopefully add it to the backlog.
