add completion for docker image pull

Browse Source 
With this patch, completion is provided for images already present
in the local image cache to help pulling the latest version of the
same tag;

    docker pull go<tab>
    golang:1.12    golang:1.18.0  golang:1.21    golang:1.24    gopher:latest
    golang:1.13    golang:1.20    golang:1.23    golang:latest

    docker pull golang:<tab>
    1.12    1.13    1.18.0  1.20    1.21    1.23    1.24    latest
