Enhance Sentry error fingerprinting

[zen-wego]

Context

Due to unoptimised fingerprinting in our existing Sentry implementation, many related events are not being grouped together.

By delegating to use the default fingerprinting algorithms in Sentry, with some additional granularity, we might be able to group events better → https://docs.sentry.io/platforms/go/guides/gin/usage/sdk-fingerprinting/

Additionally, we can accept optional parameters to enrich the event → https://docs.sentry.io/platforms/go/guides/gin/enriching-events/

Changes

• Introduced a new ErrorData struct to carry optional Extra and Tags data, giving consumers flexibility in including more detailed context in error events.
• Updated CaptureError and CaptureWarning functions to accept optional ErrorData parameters, maintaining backward compatibility while enabling additional context to be passed.
• Refactored the enrichScope function for clarity.
• Simplified the fingerprint generation logic by delegating default fingerprinting to the Sentry SDK and appending the error code for uniqueness.

Note

This PR initially contained changes that added easier attachment of tags/extras via a new ErrorData struct. To simplify the changes I've since removed them.
