feat(cli/unstable): add visibleLines and indicator options to promptMultpleSelect, and show ... above the options when appropriate

[timreichen]

After trying the api, ... seems not too intuitive, nothing indicates if there is more content above.
This PR changes the more content indication ... to a ↓ arrow and additionally it indicates if moving up is possible with a ↑ arrow. It also adds indicator and visibleLines properties to promptMultipleSelect().

Is this way of indicating 'more content' common in general? What do other tools do for this situation?

Some tools just loop over (like Inquirer select) and others don't even bother, but I find the arrows a nice fit

I personally prefer ... for indicating 'more contents' which feels more common to me.

↑ and ↓ in this context feel confusing to me. (I don't remember the use case where ↑ and ↓ indicating 'more contents')

The arrows have the additional benefit of not just indicating more contents, but also the location.
... seems fine until one scrolls and content gets out of bounds above, which is not very intuitive to me.

I think that situation can be covered by showing ... above.

Confirmed this nicely wraps the options. LGTM

Added some examples to demonstrate both patterns (full and partial) of displaying options
