/kind feature

Description

Currently podman info doesn't show the mirror info if that exist in the /etc/containers/registry.conf file the same way it show for insecure registry.

Steps to reproduce the issue:

1. Have the registry conf like following.

$ cat /etc/containers/registries
unqualified-search-registries = ["registry.access.redhat.com", "docker.io"]
[[registry]]
  location = "registry.access.redhat.com/ubi8/"
  insecure = false
  blocked = false
  mirror-by-digest-only = true
  prefix = ""
  [[registry.mirror]]
    location = "example.io/example/ubi8-minimal"
    insecure = false
