docs(react-native): Clarify profiling platform support

[antonis]

DESCRIBE YOUR PR

Adds a "Platform Support" section to the React Native profiling docs that clarifies which profiling levels are available on which platforms:

• JavaScript profiling (Hermes) works on iOS and Android
• Native profiling captures Swift/ObjC on iOS/macOS (via sentry-cocoa) and Kotlin/Java on Android (via sentry-java)
• Other platforms (tvOS, visionOS) only get JS profiling

Content looks accurate. One style note: the cross-links to sentry-cocoa and sentry-java profiling use absolute https://docs.sentry.io/ URLs. The sentry-docs convention is typically relative paths or <PlatformLink> components — absolute URLs won't benefit from any path rewriting the build system does and will silently break if those paths ever move.

EDIT: Claude posted this comment without my asking 🫠. Take it or leave it @antonis 👍

Actually that was a good catch 👍 Updated to use <Link> since < PlatformLink> only works within the same platform. Let's see if the CI is happy.
