`ls` as an alias of `list`

**Is your feature request related to a problem? Please describe.**
I'm frustrated having to use `toolbox list` instead of `toolbox ls`

**Describe the solution you'd like**
An alias to list - `ls`

**Describe alternatives you've considered**
NA

**Additional context**
NA.

Start by locating the CLI registration for the existing `toolbox list` command and check how other command aliases are defined. Add `ls` as an alias that invokes the same behavior, then run the CLI help and execute both `toolbox list` and `toolbox ls` to confirm they behave identically.
