Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/48076 JSC for Android does not implement `String.prototype.replaceAll`: {F1971791988} https://github.com/facebook/react-native/pull/47466 introduced a use of it into runtime code, breaking JSC compatibility. This.. replaces it.. with `replace`. Since the argument is already a regex with a `g` modifier, `replaceAll` wasn't necessary anyway.
