Setup `bash`/`zsh` command-line completion for `nargo`

[michaeljklein]

Problem

Tab-completion in bash and zsh for nargo would be helpful so that typing partial commands like nargo co<TAB> or nargo n<TAB>, the commands are completed to nargo compile, nargo new, respectively.

Happy Case

Setup tab completion for the commonly used shells bash and zsh

Workaround

Yes

Workaround Description

1. Use "short" versions of commands where available (e.g. check, execute) or else enable them for other commands
2. Type the whole command
