Slide navigation broken on mobile

It appears the swipe gesture is not working, and mdx-deck slides are not able to be viewed on mobile devices.

I tested this on an iPhone and and Android device and both were unable to get past the first slide.

Steps to reproduce:

1. Follow readme instructions to create a minimal deck (deployed here for testing: https://foo-489.netlify.app) using the latest version of mdx-deck (4.1.1)
2. Try to swipe on a mobile device— you are not able to proceed to slide 2.
