fix(iOS,Fabric): fix MUTATION_PARENT_TAG definition when using dynamic frameworks (#2737)

## Description

It seems that '-' characters in import names are swapped for '_' when
using dynamic frameworks,
therefore we need to check not only for `React-RCTAppDelegate` but also
for `React_RCTAppDelegate`.

## Test code and steps to reproduce

Build with `USE_FRAMEWORKS=dynamic` now passes.

## Checklist

- [ ] Ensured that CI passes
