Fixed webhook alert delivery and improved input and action configuration:

• Fixed the Alert Notification Events trigger to register its Datadog webhook against the deployed flow's own URL, so alert notifications are now delivered in flows with any name
• Grouped the optional metric configuration and resource inputs on Submit Single Metric into a Metric Fields structured object; Tags remains a top-level input
• Added inline action calling support across all actions so the app builder can show example output during configuration
• Added output schemas to actions for improved field mapping

Updated spectral version

Initial release of the Datadog component with support for submitting metrics, managing webhook integrations, and receiving monitor alert notifications via the Alert Notification Events trigger
