[TextInput]: Add missing value 'go' in enterKeyHint prop

[tarunrajput]

enterKeyHint supports following values but docs are missing one value go. Also, enter is equivalent to UIReturnKeyType default and supported in iOS only.

export type enterKeyHintType =
  // Cross Platform
  | 'done'
  | 'go'
  | 'next'
  | 'search'
  | 'send'
  // Android-only
  | 'previous'
  // iOS-only
  | 'enter';

@Simek, could we merge this?

I believe yes, not sure why @Simek you added "Waiting on future release"

[Simek]

I believe that I have added labels since at te moment of PR publish, changes has not been merged to core repo yet, and thus was not sure when they land and which version the changes be a part of. Usually we update those labels in docs after the PRs land, or when preparing docs cut for new version.

@tarunrajput Can you backport the changes to versioned 0.73 docs before we ship this out, since this change has landed as a part of this release?
