docs(exceptions): update exception types and remove tracing (#1652)

* docs(exceptions): update exception types and remove tracing

- Updated the list of exception types to reflect additional integration-
  specific exceptions in the guardrails library.
- Removed detailed descriptions and Colang examples for each exception
  type, consolidating documentation.
- Deleted the section on integration with tracing, including guidance
  and references to tracing configuration.

 ## Exception Types
 
-NeMo Guardrails supports several predefined exception types:
+The NeMo Guardrails library includes additional exception types for specific integrations:
 
-### InputRailException
+- `LlamaGuardInputRailException` / `LlamaGuardOutputRailException`
+- `JailbreakDetectionRailException`
+- `ContentSafetyCheckInputException` / `ContentSafetyCheckOutputException`
+- `FactCheckRailException`
+- `SelfCheckHallucinationRailException`
+- `InjectionDetectionRailException`
 
-Raised when input rails block or reject user input.

-```colang
-define flow custom input check
-  if $user_message contains "forbidden_word"
-    create event InputRailException(message="Input contains forbidden content.")
-```

-### OutputRailException
-
-Raised when output rails block or reject bot responses.
-
-```colang
-define flow custom output check
-  if $bot_message contains "sensitive_info"
-    create event OutputRailException(message="Output contains sensitive information.")

-### DialogRailException
-
-Raised when dialog rails encounter issues during conversation flow.
-
-```colang
-define flow topic restriction
-  if $user_intent == "ask_about_restricted_topic"
-    create event DialogRailException(message="This topic is not allowed in the current context.")

-```colang
-define flow retrieval validation
-  if len($relevant_chunks) == 0

-## Integration with Tracing
-
-Exceptions are automatically captured by the tracing system when enabled. This allows you to:
-
-- Monitor exception frequency and types
-- Track which rails are triggering exceptions
-- Analyze patterns in user inputs that cause exceptions
-- Debug and improve rail configurations
-
-For more information on tracing, see the [Tracing Configuration](tracing-configuration.md) guide.
