Update zot Admin guide section "Building and deploying a zot container image from source"

[andaaron]

Update section http://zotregistry.io/docs-zot/zot-docs-1/1.0/admin-guide/admin-guide.html#_building_and_deploying_a_zot_container_image_from_source

Current questions which need to be answered and documentation updates:

1. Does the 'make image' command use the Dockerfile? Wouldn’t we use a docker command?
2. How do we specify the inclusion of zli and zb binaries in the container?
