#4253 upgrade jsc

[josh-griffin]

Fixes #4253 - doubt it!

Change summary

• Bugsnag bump: https://github.com/bugsnag/bugsnag-js/releases - seem to be a lot of bug fixes, some crashes 🤷
• JSC new version for the first time in like 3 years https://github.com/react-native-community/jsc-android-buildscripts/releases/tag/v250230.2.1 - need to wait for RN to start using it, usually, but can force it. It has this fix which looks promising, to me! GC concurrent issue potential fix Kudo/jsc-android-buildscripts#1 - Can check the JSC loaded on your app using adb logcat | grep "JavaScriptCore.Version"

Testing

• App runs and works

Related areas to think about
