`dvc diff --show-hash --show-md <commit>` shows only file paths, doesn't show md5 hash

Bug Report

dvc diff command has option to --show-hash for debug purpose.

Also the output can be formatted to json or md using --show-json and --show-md option.

Currently --show-hash works fine with normal output and --show-json. It is not showing hash for --show-md.

Example:

Normal Text

~ dvc diff --show-hash b34c3e4
Modified:
    84f9553c..201bc54b  data/models/ensemble/metrics.csv
    f9298672..2db2b3bc  data/models/ensemble/model.gz
    f858c58a..aa2ba7d8  data/models/logistic/metrics.csv
    24d7f7f2..00a3ccdf  data/models/logistic/model.gz

Json format:

~ dvc diff --show-hash --show-json b34c3e4
