Motivation and Context

• In GitFlow, develop is the main integration branch where feature branches are regularly merged.
• Developers working on long-lived feature branches can easily fall out of sync with develop.
• This notification ensures the team is immediately aware when develop changes — encouraging timely rebases and reducing the likelihood of complex merge conflicts later.

Description

• Introduces a GitHub Actions workflow that sends a notification to Microsoft Teams when a push is made to the develop branch. It integrates with a Power Automate flow via a secure HTTP POST request.
• GitHub secret DEV_MERGE_TEAMS_URL configured
