Add @microsoft/react-native-clarity

[Jayesh-JainX]

📝 Why & how

Adds @microsoft/react-native-clarity to the directory.

Microsoft Clarity is an analytics tool that helps you understand how users interact with your React Native app through session recordings and heatmaps.

Closes #2397

✅ Checklist

• Added library to react-native-libraries.json

[Jayesh-JainX]

Note: The @microsoft/react-native-clarity package lists
github.com/microsoft/clarity-apps as its repository on npm,
but that repo is a Swift distribution repo with no package.json.
The npm package name cannot be verified from the GitHub URL via
the validator. Flagging this for maintainer review.

Hey @Jayesh-JainX,

thanks for proposing a new entry, but unfortunately we only support open-source libraries, so @microsoft/react-native-clarity cannot be added.
