allow scrolling in MD code

[embiem]

When I want to scroll a code example in MD in any readme to left or right, the app actually tries to switch e.g. from home area to notification area.

Expected:
When tapping first inside a code example in MD, hold the tap and move, then I'd expect that the actual embedded code preview is scrolled.

I'd like to tackle this issue myself as a first contribution, if you agree that this is an issue that needs to be fixed.

@MBEIERL Sure. Welcome to GitPoint!

But I didn't re-produce this problem when visiting readme of my project (iPhone 6P, iOS 11.1, GitPoint 1.3). Can you provide your test project, app version and device information?

Confirmed on Android, as soon as you try to scroll a <code> block, react-navigation swipe kicks in and wants to switch tabs:

@MBEIERL Thank you a lot for logging this issue! I remember we talked about in #326 (comment)

We'll be more than glad if you can give this issue a fresher look!

Seems like react-native-navigation latest version allow disabling the swipe gesture for a particular screen.
Could that be an acceptable fix for markdown enabled screen on Android @housseindjirdeh ?
