ci(alert): Configure rootly to send alerts to multiple services

[rbarker-dev]

Description

This pull request updates the Rootly integration in both the node-flow-build-application.yaml and zxcron-extended-test-suite.yaml GitHub workflow files. The main goal is to support multiple Rootly services for notifications, improve clarity in workflow outputs, and ensure alerts are sent to all relevant services.

Rootly Integration Improvements:

• Added support for notifying multiple Rootly services by introducing the ROOTLY_SERVICES variable and updating workflow outputs and alert payloads to use this list. [1] [2] [3] [4]

Workflow Output and Summary Enhancements:

• Changed workflow outputs from a single service to service-target and services, and updated summary sections to display both the notification target and all relevant services for better visibility. [1] [2]

These changes help ensure that incidents and notifications are correctly routed to all impacted Rootly services and improve the transparency of workflow status reporting.
