// Sort sorts string references preferring higher information references.
//
// The precedence is as follows:
//
//  1. [Named] + [Tagged] + [Digested] (e.g., "docker.io/library/busybox:latest@sha256:<digest>")
//  2. [Named] + [Tagged]              (e.g., "docker.io/library/busybox:latest")
//  3. [Named] + [Digested]            (e.g., "docker.io/library/busybo@sha256:<digest>")
//  4. [Named]                         (e.g., "docker.io/library/busybox")
//  5. [Digested]                      (e.g., "docker.io@sha256:<digest>")
//  6. Parse error
