The `VirtualSize` field was deprecated in [moby@1261fe6], and omitted / removed in API v1.44 in [moby@913b0f5], and the corresponding formatting placeholder was deprecated in [cli@f02301a]. This patch removes the formatting function, which also removes it from the `docker image ls --format=json` output.
