bug: swipe to close modal does not use custom animation

[liamdebeasi]

Bug Report

Ionic version:

[x] 5.x

Current behavior:

Modal with custom leave animation is not used when swipeToClose = true. The standard card-style animation is used.

Expected behavior:

I would expect that users can provide a custom animation to the swipe to close modal.

Steps to reproduce:

1. Open https://codepen.io/ionic/pen/ExapZBZ.
2. Set modalElement.mode = 'ios'.
3. Set modalElement.swipeToClose = true.
4. Open modal and attempt to swipe closed.
