Comment 2 for bug 1975901

https://git.launchpad.net/simplestreams/tree/simplestreams/mirrors/glance.py?id=18c7d6300a31305978f3871333ba8990262f4bef#n458

By following the naming convention in the title of https://cloud-images.ubuntu.com/releases/focal/release/, a friendly name can be:
"Ubuntu 20.04 LTS (Focal Fossa) <arch> <date>" or something like that.

so
"{os} {release_title} ({release_codename}) {arch}"
-> ubuntu 20.04 LTS (Focal Fossa) amd64

However, there is no capital "U" for Ubuntu and there is no dedicated field for the date. Missing date may not be critical but it's confusing to have multiple images with the same name when `--max` is specified with more than 1.
