'aspire add' search feature does not provide a way to go to next matched one

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Describe the bug

In 'aspire add' after typing to search it goes to the first matched one but if i want to see the next matched one i should scroll the list manually

### Expected Behavior

I think one of these should happen:
1) the list should be filtered while typing, which is currently being highlighted
2) add some shortcut for going to next/prev one

I prefer the first option

### Steps To Reproduce

1) run aspire add
2) search for sth like 'redis'
