Replace Equinix CentOS8 system with a supported OS

[sxa]

CentOS 8 is end of life.However, one of our Altras is still running it so we should replace it with another offering. The ones which Equinix offer on these systems are:

• CentOS8
• Debian 10
• Ubuntu 20.04
• Custom PXE

NOTE: I've removed dockerBuild from this machine as the docker-build-multiarch job was failing on it with this error:

$ docker login -u adoptopenjdkuser -p ******** https://index.docker.io/v1/
Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.
Error: credentials key has https[s]:// prefix

Ubuntu 22.04 has now been added as a valid option for the x.large.arm servers at Equini so we should be able to push this up now. Will spin out a separate issue for it.
