This commit enables `Fabric` and `Hermes` for `iOS` and in my initial tests the app seemed to behave well.
We can't do this for Android yet because the blur view implementation is not ported to `Fabric` properly.
needed for https://github.com/status-im/status-mobile/issues/18138
Possible fix for errors like:
```
bundler: failed to load command: fastlane (/Users/jenkins/.bundle/ruby/2.7.0/bin/fastlane)
/Users/jenkins/.bundle/ruby/2.7.0/gems/fastlane-2.205.2/fastlane_core/lib/fastlane_core/ui/interface.rb:153:in `shell_error!': [!] Shell command exited with exit status 51 instead of 0. (FastlaneCore::Interface::FastlaneShellError)
```
