fix(go-sdk): document SetAttributes/RemoveAttribute and Extra deprecation migration

[Copilot]

PR getsentry/sentry-go#1224 formally deprecated Scope.SetExtra, SetExtras, and RemoveExtra and added Scope.RemoveAttribute. The skill's scope API reference was missing the new method and lacked migration guidance.

Changes to references/error-monitoring.md

• Scope API table: Added SetAttributes and RemoveAttribute; moved SetExtra/SetExtras/RemoveExtra into a clearly marked deprecated section with inline migration pointers
• Migration block: Added concrete before/after examples covering both use cases (error events → SetTag/SetContext, logs & metrics → SetAttributes/RemoveAttribute)
• Best Practices: Replaced the vague "Extra is deprecated" note with two specific guidelines distinguishing error-event enrichment from attribute-based log/metric enrichment

// Before (deprecated)
scope.SetExtra("key.string", "str")

// After — error events:
scope.SetTag("key.string", "str")
scope.SetContext("my_data", sentry.Context{"key.int": 42})

// After — logs and metrics:
scope.SetAttributes(attribute.String("key.string", "str"))
scope.RemoveAttribute("key.string")

SDK Changes Detected

The following PR was merged to getsentry/sentry-go in the last 7 days that may affect the sentry-go-sdk skill:

• feat: add RemoveAttribute api on the scope sentry-go#1224 — feat: add RemoveAttribute api on the scope (feat: add RemoveAttribute api on the scope sentry-go#1224)

Potential Skill Gaps

1. Deprecated APIs: PR #1224 formally deprecates Scope.SetExtra, Scope.SetExtras, and Scope.RemoveExtra in favor of Scope.SetAttributes and Scope.RemoveAttribute. The skill's references/error-monitoring.md already notes SetExtra as deprecated, but the scope API table (line 293) does not yet reflect the full migration path or the new RemoveAttribute method.

2. New API: Scope.RemoveAttribute is now a public method and part of the recommended API. It is not listed in the scope API reference table in references/error-monitoring.md.

   The recommended migration path from the PR:

   • For error events: use SetTag / SetContext instead of SetExtra
   • For logs and metrics: use SetAttributes / RemoveAttribute

   // Before (deprecated)
   scope.SetExtra("key.string", "str")
   scope.SetExtra("key.int", 42)
   
   // After (for error events)
   scope.SetTag("key.string", "str")
   scope.SetContext("my_data", sentry.Context{"key.int": 42})
   
   // After (for logs and metrics)
   scope.SetAttributes(
       attribute.String("key.string", "str"),
       attribute.Int("key.int", 42),
   )
