Missing accessibility options in EnrichedMarkdownTextInput

[mmiedlarz]

Describe the bug
There are two issues that are related to a11y while using TextInput:

1. Missing any RN accessibility props to pass to EnrichedMarkdownTextInput
2. While in VoiceOver mode, it lacks "Text Input" role, so it's not announced as editable by VoiceOver

To Reproduce
Steps to reproduce the behavior:

1. Render two components: EnrichedMarkdownTextInput and regular RN TextInput on single screen.
2. Enable VoiceOver (on iOS - by pressing side button 3 times). It might be helpful to hide curtain so you'll see what's on the screen.
3. Using swipe-left and swipe-right gesture, select EnrichedMarkdownTextInput - notice that you're able to select it but VoiceOver will miss text input information.
4. Select regular TextInput - notice that it'll announce correct type

Expected behavior

1. Ability to provide accessibility props to EnrichedMarkdownTextInput
2. Correct VoiceOver type

Screenshots

Hi @mmiedlarz thanks for the bug report! This should be fixed in next nightly release!

Readability done in #526

Note: improving the "writeability" on IOS will be much harder to do and would require doing a bunch of changes to architecture of input, so we will not pursue it for now
