nerctl inspect returns invalid json for multiple containers

[flokain]

Description

When running nerdctl inspect ....it returns invalid json in form of [{container1}][{container2}] instead of [{container1},{container2}]

This causes colima to fail with --mount-inotify --runtime containerd. see abiosoft/colima#910 (is closed but not fixed)

Steps to reproduce the issue

1. sudo nerdctl --namespace 'k8s.io' inspect 4722f9cfc4f3 df6e66bf279e
