Copy release script in the master branch to hotfix branch when creating a hotfix branch

[pavinduLakshan]

Purpose

$subject

This is done due to the hotfix workflow for identity-apps was added recently and therefore the related changes to release script are not present in the older app versions. We may be able to remove this line once the older app versions are old enough, as by that time, the updated release script will be universally available in app versions that need to be hotfixed.
