use Everything for docker and make disk size bigger
    
    minimal container image says it needs more disk space so bump
    size to 5G
    use the Everything repo for the container images, microdnf
    is not part of the cloud variant and it really does not make
    ense to add it nor to make a container Variant with its own
    install tree
