Document command aliases

[GrigoriyMikhalkin]

Some commands like docker ps, docker history have aliases (docker container ls, docker image history), which causes some confusion among new users(1, 2).

It probably would be helpful, along with parent command and related commands in docs, specify alias commands too.

Really? Nothing? I just spent an hour looking for explicit documentation that "docker run" and "docker container run" (etc etc etc!) are actually the same command and that I wasn't being gaslighted.

This was implemented in docker/docs#19045 (and various related changes); docs now mention aliases;
