Making auto Milestone for critical issues each month

This MR aims to introduce an automated process that creates monthly milestones for issues related to bug fixes or hotfixes that arise unexpectedly and completely spontaneously from user feedback. These issues often fall outside our long-term planning, and to effectively manage them, we have implemented a pipeline that automatically generates a milestone titled "NUKLEUS Emergency Patch ${MONTH-YEAR}" each month. This milestone will serve as a dedicated space to organize and plan for tickets and tasks that arise spontaneously, ensuring that they are addressed promptly and efficiently. It triggers via a scheduler, please feel free to change it to the time you feel fits better

and also pipeline gets triggered just via schedulers. Feel free to generates milestone and remove it via play button.

I will be thankful if you review this
