Fix Hermes not available on iOS when use_frameworks enabled (#3491)

## Description

When there are frameworks used and Hermes enabled in the Podfile of your
project, RN falls back to JSC in debug mode and crashes in production
mode.

This PR makes it possible to use Hermes when there is `use_frameworks!`
enabled in the Podfile.

Thanks @Kudo who originally fixed this issue in ReactNative repository:
facebook/react-native#34222

## Changes

Added path to `Framework Search Paths` in Podspec of
react-native-reanimated.

## Test code and steps to reproduce

1. Create empty ReactNative project
2. Add react-native-reanimated dependency.
3. For ReactNative 0.69.3 apply patch from:
https://github.com/facebook/react-native/pull/34222/files
4. Enable frameworks in Podfile: `use_frameworks! :linkage => :static`
5. Build project in debug mode -> you will not see `engine: hermes` in
top right corner.
6. Build project in release mode -> app will crash at startup
