Twilio android ref fix

[itz-Me-Pj]

This PR fixes the issue #774 . Also updated the documentation as per new react-native arch v0.79+. This issue has been bugging me for a couple of weeks now thought pushing the changes myself would help the community. Had to figure out the solution myself for the problem. 😅

@gastonmorixe @bilby91 @slycoder Sorry to bother you guys but can you please review and merge this PR as I think the CircleCi pipeline isn't going to proceed further.(as seen in past opened PRs). This change is crucial for my development because in order to fix the issue I have to manually add the change in the node modules. And every time it gets cleaned I have to reimplement the change in the node modules to get the expected result

I manually applied your changes locally and my app now runs, thanks, +1 for getting this merged in to support the new arch

That explains it. This library has been complaining about a deprecated string ref for a long time. There has been an issue for it but was ignored for a year.

thanks for this - applied via a manual patch to get this working after upgrading react native
