[CICD][DEPLOY] Refactor DEPLOY_DATE calculation

DEPLOY_DATE is used in artifact naming. Previously, it was derived using the local date command, which could lead to inconsistencies. Specifically, if a pipeline started just before midnight and some jobs ran after midnight, artifacts from the same release pipeline could end up with different DEPLOY_DATE values.

This commit updates the DEPLOY_DATE calculation to use the CI_PIPELINE_CREATED_AT value instead, ensuring that all artifacts share a consistent date based on the pipeline's start time, rather than each individual job's execution time.
