ci: consolidate ISO workflows into single dual-mode build-iso

Merge build-iso.yaml and build-iso_more-recent.yaml into one workflow.
- triggers: push to main (build + artifact) and v*.*.* tags (build + release)
- parametrize Fedora version and dish via env
- fix copyin source (cook/dishes/... .cfg) and artifact/release path
  (host path into the mock chroot, /var/lib/mock//root/var/lmc)
- install cook Python deps in the build job before make all
- drop build-iso_more-recent.yaml (superseded)
