docs(modal): document isDismissing on ModalDragEventDetail

[thetaPC]

Issue URL: ionic-team/ionic-framework#31001

What is the current behavior?

ModalDragEventDetail documents currentY, deltaY, velocityY, progress, and snapBreakpoint. The isDismissing property added in ionic-framework#31002 is
undocumented, so there is no reference for when it is true or which event includes it.

What is the new behavior?

Documents isDismissing in the ModalDragEventDetail interface:

• When it is true for sheet modals, snapping to a breakpoint of 0, and for card modals, passing the threshold required to close.
• That a canDismiss callback can still cancel the dismiss after the event is emitted, and that ionModalDidDismiss confirms the modal closed.
• That the property is only included on ionDragEnd, not ionDragMove.
• A use case, reacting as soon as the user releases the modal, such as dismissing the keyboard.

Does this introduce a breaking change?

• Yes
• No
