✨ Adds Discord notifications for bug issues

Adds a new workflow to send notifications to Discord when a new "Bug" type issue is opened.

Significant changes include:
- Creates a new workflow file for issue notifications.
- Configures the workflow to trigger on issue creation events, specifically for issues labeled as "Bug".
- Implements a step to send a formatted message to a Discord channel using a webhook URL.
- Includes the issue title, author, link, and a truncated description in the Discord message.
- Deletes the AI code review workflow
