Need ubuntu 20.04 and/or 22.04 ARM Helix queues

[MattGal]

Today, we have ubuntu.1804.armarch and ubuntu.1804.armarch.open to service virtually all our ARM64 Linux scenarios (via docker-ized work items / direct execution).

Our users will need to have in place a similar solution when (per their wiki) in April 2023 18.04 is fully out of support.

@ilyas1974 suggests: "My thought was to creat a new 2004 queue in Dec and have DDFUN “upgrade” ~50 systems. Once people get back from the holidays, we start migrating customers."
