Resolve upstream ReactNative android build blocker

[Julesssss]

Problem

Facebook broke Android builds last Friday, here's a full breakdown of the cause.

Solution

To fix, we should bump React Native to the latest hotfix release, to resolve an Android build issue that is blocking us from making Android releases.

Manually set the gradle RN version.

This is being handled internally, no need for contributors.

Okay, so the hotfix is only a few hours old, so the RN-updater and diff table haven't yet been updated.

I assume there are likely no breaking changes, but given that we have previously made changes ourselves, I wonder if it's worth attempting this simple fix in the meantime...

Essentially, we would simply lock our gradle react native version to our current RN version.

The above fix is even simpler than this, as it doesn't require a React-native bump, or library deploy. I'm going to make this change locally in App and if it works we can discuss next steps.
