Fix zsh completion

[ad-chaos]

Before we were implicitly declaring the opts and coms arrays, which had the undesired effect of zsh parsing it as an associative array instead of a normal array.

Now we explicitly declare the opts and coms arrays to be normal arrays.

As an aside it would be nice to test whether the completions are working or not.

One way I couls think of doing it would be via running the _complete_debug widget and checking if there are no error messages in it.

Did you test those changes manually?

[ad-chaos]

You mean?

[Secrus]

I meant, did you install these completions locally and tested that they work properly?

[ad-chaos]

Yes I did. You can try it yourself with the example in the readme :)
