Document and test ErrorBoundary

[bruno-garcia]

Perhaps some of the JS docs could be moved to an include and reused.
But here we need to document why it's needed vs bubbling to the unhandled exception integration.
And when/how the white screen rendering happens.

We have a user reported issue that the fallback isnt' working on React Native. Consider adding this test case to e2e.

@bruno-garcia can you link where this is already documented for JS?

I guess its https://docs.sentry.io/platforms/javascript/guides/react/components/errorboundary/
just to confirm, is it a React thing only?

Sorry, I don't keep up with GH notifications anymore. Please drop me a link via DM if I'm blocking?

Yes

Is ErrorBoundary (import { ErrorBoundary } from '@sentry/react-native') supposed to be used & working?

I can't find docs about it but the export from @sentry/react-native definitely exists.
