Notification for Promoting Pre-Releases to Latest Releases

[mazlan25]

Is your feature request related to a problem?
Please describe.
Currently, the GitHub-Slack integration does not send notifications when a pre-release is promoted to a latest release. This creates a communication gap, as our team does not get notified when production deployments happen. Additionally, the integration does not allow us to customize the notification messages, which limits the ability to provide relevant context or format the notifications according to team preferences.

Describe the solution you'd like

1. Notification for Promoting Pre-Releases to Latest Releases:
   • Add support for Slack notifications when a pre-release is promoted to a latest release.
   • Include the relevant details, such as release version, associated changes, and links to the release.
2. Feature to Edit Notification Messages:
   • Allow customization of Slack notification messages, such as:
     • Modifying the message format.
     • Adding custom text or links.
     • Including specific tags or mentions for relevant team members.
     • Adding environment variables for deployment on different environment during pre-release and latest-release

Additional context

Our team uses GitHub-Slack integration extensively to track release updates, especially for automated CI/CD pipelines. Notifications for promoting pre-releases to production (latest release) are critical for ensuring everyone is aligned on production changes.
Example scenarios where this feature would be helpful:

• Notifying the team about a production deployment triggered by promoting a pre-release.
• Customizing messages to include specific instructions or tagging key team members for immediate follow-up or for stating which environment deployment was done.
