cli: report error if arguments are given for subcommands that require no arguments

[k1LoW]

I use Colima conveniently every day. Thank you.

When I have multiple profiles, I have deleted the environment several times by running the following command by mistake.

$ colima list
PROFILE    STATUS     ARCH       CPUS    MEMORY    DISK
default    Running    aarch64    8       8GiB      128GiB
x64        Running    x86_64     8       8GiB      128GiB
$ # I want to delete `x64` profile !!
$ colima delete x64 # !!!???
are you sure you want to delete colima and all settings? [y/N] y

This pull request is a fix to make error if arguments are given for subcommands that require no arguments.

Yeah, thanks. I actually considered handling extra argument for start, stop and delete as the value for --profile.

It feels intuitive that a user would expect colima delete x86 to mean delete the x86 profile.

Thank you for merging!

Looks good to me 👍
