[arslankhanali]

What would you like to be added:

At (https://github.com/redhat-et/microshift-documentation/blob/60ff164ed9e95e05eeb5e69827e4d722955ebf32/content/en/docs/user-documentation/how-tos/acm-with-microshift.md) KlusterletAddonConfig is missing version

Why is this needed:

User will get an error/prompt for version otherwise

fix:

cat <<EOF | oc apply -f -
