Fix HERMES_ENABLE_DEBUGGER define for jsinspector-modern under CocoaPods

Summary:
> [!Note]
> Replaces facebook#46282.

We intended to enable Fusebox on `main` since facebook#45469 — this worked when building under Buck, however was not working for builds under Xcode. This is because the `HERMES_ENABLE_DEBUGGER` preprocessor flag was missing for the `React-jsinspector` Podspec.
