Skytap Linux/ppc64 capacity restricted due to Ubuntu being unavailable on POWER8

[sxa]

We were recently migrated from Skytaps's POWER9 in their Amsterdam data centre to older generation POWER8 systems. Ubuntu 22.04+ does not support POWER8 and there is no template available for Ubuntu 20.04 in that location.

At the moment this means that many of our test-docker ppc64le machines are offline Ref: https://ci.adoptium.net/label/hw.dockerhost.dockerhost-skytap-ubuntu2204-ppc64le-1/
