Helm charts: initial job run

[rayrapetyan]

When deploying k8s-ecr-login-renew via the helm chart (and likely any other method), it's advantageous to execute an initial job run immediately after installation. This aligns with the standard practice that every user typically follows, as outlined in the documented kubectl command:

kubectl create job --from=cronjob/k8s-ecr-login-renew-cron k8s-ecr-login-renew-cron-manual-1
