1. Add the required trigger_settings field.

The trigger_settings parameter was added in commit c930d9eef8 on
March 4, 2025 in PR #26086:
"feat(processing_engine): error handling for triggers."

It replaced the previous flags: Vec field in
ProcessingEngineTriggerCreateRequest.

The TriggerSettings struct contains:

• run_async: bool - Whether to run the trigger asynchronously
• error_behavior: ErrorBehavior - How to handle errors (Log, Retry,
  or Disable)

2. Fix docs audit script in influxdata/docs-tooling
