Make fmt and SocketRocket compatible with Swift (#50874)

Summary:
`SocketRocket` and `fmt` are part of React Native dependencies.
If a library is written in swift and depends on them, it will fail to install the pods because these pods are not compatible with Swift.

This change makes sure that the pods are installed in a way that is swift compatible.

## Changelog:
[iOS][Fixed] - Make fmt and SocketRocket Swift friendly

Pull Request resolved: https://github.com/facebook/react-native/pull/50874

Test Plan:
Tested locally in a nightly app.

### Before the change:

```
yarn add react-native-video
cd ios
bundle exec pod install
```

This script resulted in this error:

```
[!] The following Swift pods cannot yet be integrated as static libraries:

The Swift pod `react-native-video` depends upon `fmt` and `SocketRocket`, which do not define modules. To opt into those targets generating module maps (which is necessary to import them from Swift when building as static libraries), you may set `use_modular_headers!` globally in your Podfile, or specify `:modular_headers => true` for particular dependencies.
```

### After the change

```
yarn add react-native-video
cd ios
bundle exec pod install
```

This script installed pods successfully.
