fix(spotlight): Stop tracing Sidecar network request in JS

[krystofwoldrich]

📢 Type of change

• Bugfix
• Enhancement
• Refactoring

📜 Description

The current approach makes the network request from the Spotlight Integration to the Sidecart visible in breadcrumbs, performance, and errors if one occurs. This PR changes to the StealthXhr implementation which uses the __sentry_original__ methods, so the calls are not traced by Sentry.

💚 How did you test it?

📝 Checklist

• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled
• All tests passing
• No breaking changes
