Aliases do not produce the same help docs

[purplecabbage]

I am not sure if it is recent Oclif changes, or our own extensive command/topic aliasing but using rt in place of runtime produces much less context in --help

 aio runtime action --help
Manage your actions

USAGE
  $ aio runtime action [--cert] [--key] [--apiversion] [--apihost] [-u] [-i] [--debug <value>] [-v] [--version] [--help]

  -u, --auth       whisk auth
  -v, --verbose    Verbose output
  --apihost        whisk API host
  --apiversion     whisk API version
  --cert           client cert
  --debug=<value>  Debug level output

  --key            client key
  --version        Show version
