Failure to build due to Facebook/Meta issue

Since Nov 4th this will fail to build due to facebook/react-native#35210.

Fix coming soon, just need to update to react-native@0.66.5

Ok this is super frustrating. Updating seems to cause react-native-v8 to crash see #1040.

I tried updating react-native-v8 to v1.5.2 (latest) but that seems to be broken right now: Kudo/react-native-v8#149

We can't stick to react-native@0.66.4 because it now fails to build because Facebook published to Maven Central.

Possible ways forward:

1. Wait for a fix to either RUNTIMEEXECUTOR_LIB set to NOTFOUND Kudo/react-native-v8#149 or crash with null pointer dereference react-native v0.66.5 Kudo/react-native-v8#150
2. Switch to JSC, remove react-native-v8 from project

(2) would have the impact of potentially higher memory usage on low-end devices that with react-native-v8. Switching ti Hermes would likely have similar benefits to react-native-v8, but Hermes does not fully support Intl (which we use) in v0.66, so we would need to update react-native to v0.70.0.

Possible best way forward: Switch to JSC, accept memory/performance cost.
