fix: Update release version naming in GitHub API call

Corrected the API call to fetch release details by properly adding 'v' before the RELEASE_VERSION in the request. Moreover, added a check for the name attribute of the returned URL instead of the URL string itself, ensuring the release creation calls function properly when no previous release exists.
