pacman-helper.sh: set release name to be the same as tagname

I noticed the latest release created picked up its name from the latest commit to the main branch in the pacman-repo repository, namely "2025-02-26T22-44-26.725080300Z: Merge pull request #1 from git-for-windows/populate-the-readme".  Given that it's very unlikely that the commit(s) on the main branch have anything to do with the releases, just specify the name to be the same as the tagname.
