The reference filter docs only showed busybox globs and never said what a "reference" actually is.

Spell out that it's REPOSITORY:TAG (registry host/port included in the repository path) and that globs match the full string — which is why something like acme can miss docker-registry…acme.com:5000/… names.

Fixes #3654

Spell out that reference is REPOSITORY:TAG (including registry host/port
in the repository path) and that globs match the full string, which is
why patterns like *acme* can miss private-registry names.

Fixes docker#3654
