Added observability to Composable Commerce SDKs

We have added support for New Relic to Composable Commerce SDKs.

New Relic is an observability platform which monitors your application's performance. This integration helps you analyze your application to identify potential improvements for performance and user experience.

With this update, you can:

• Trace and profile application performance directly from the SDK.
• View and analyze your application's performance.
• Get real-time insights and alerts about your application's performance and issues.

New Relic is currently supported by the latest versions of the Java SDK, TypeScript SDK, PHP SDK, and .NET SDK.
