ADD(cronjob <-> helm chart) Need to a create a cronjob which will pull the latest image in every month

[RAJANAGORI]

Currently, Nightingale deployment in our Kubernetes architecture relies on a static Docker image. To ensure that our application stays up to date with the latest improvements and security patches, it's essential to automate the process of updating the Docker image in every month.

I propose enhancing our Helm chart to include a feature that automates the monthly update of the Nightingale Docker image within the Kubernetes cluster. This enhancement will streamline the maintenance process and ensure that our application benefits from the latest features and security enhancements without manual intervention.
