Add new architectures to openhorizon-tested-versions.txt

[bencourliss]

The openhorizon-tested-versions.txt file only has amd64 versions in it.

{
    "amd64_agbot": "2.30.0-952",
    "amd64_anax": "2.30.0-952",
    "amd64_anax_k8s": "2.30.0-952",
    "amd64_cloud-sync-service": "1.9.6-952",
    "amd64_exchange-api": "2.105.0-795",
    "amd64_vault": "1.1.1-433",
    "sdo-owner-services": "1.12.0-704"
}

A request was made to have other architectures represented in this file as well. It is worth mentioning that e2edev testing is not performed against those other architectures.
