fix get release date

[alokgoswami-ag]

This PR enhances the fetch_release_date function in the automation script to handle cases where the release "Created" date is not directly available on the release page.
It now includes fallback logic to extract the created date from the changelog (https://ppc64le.ocp.releases.ci.openshift.org/changelog) when required.
