Fix React-RCTAnimatedModuleProvider build failures (#57252)

Summary:
`React-RCTAnimatedModuleProvider` could fail to build because of two issues in its podspec:

- **Missing space between compiler flags**: `new_arch_enabled_flag` and `js_engine_flags()` were concatenated without a separator, producing a single malformed flag (e.g. `-DRCT_NEW_ARCH_ENABLED=1-DUSE_HERMES=1`) instead of two distinct flags.
- **Missing Yoga dependency**: the pod uses Yoga headers (through `React-Fabric/animated`) but did not declare the `Yoga` dependency nor its private header search path, leading to a `'yoga/...' file not found` build error.

This adds the missing space, declares the `Yoga` dependency, and adds `$(PODS_ROOT)/Headers/Private/Yoga` to the header search paths.

## Changelog:

[IOS] [FIXED] - Fix React-RCTAnimatedModuleProvider build by adding the missing Yoga dependency and a missing space between compiler flags

Pull Request resolved: #57252

Test Plan:
Without these changes, building the pod fails with errors such as:

```
fatal error: 'yoga/Yoga.h' file not found
```

and the macro flags being mangled into a single unrecognized define.

- Run `pod install` and build the app on iOS.
- Confirm `React-RCTAnimatedModuleProvider` compiles and the build succeeds.
