[Core] Remove add_command_alias (ray-project#58719)

`add_command_alias` deepcopy the `Command` object but it's no longer
deep-copyable:
pallets/click#3065 (comment). We
can remove it completely since it just creates some command aliases that
have been deprecated for 5+ years.

Closes ray-project#56747
