Michał Pierzchała 17292c9db2 Make Jest transform @react-native-community packages by default (#24294)
Summary:
Currently, `react-native` Jest preset will not automatically transpile extracted Lean Core modules (all under `react-native-community` org), so maintainers will likely need to update their docs on how to do that (it's a common pain in RN testing story).

We can make it easier for users and maintainers by adding RNC modules to the `transformIgnorePatterns` whitelist we have in Jest preset. Some of them are not necessary to transpile, but I'd say it's a small sacrifice to make (having first test run possibly slower) for having less friction around migrating to extracted modules.

[General] [Added] - make Jest transform react-native-community/ packages by default
