Add Disabled State to Options about huh

[maaslalani]

Hey! Thanks so much for creating this issue!

I'm curious on what your exact use case is here. Why would you prefer an option to be disabled rather simply removing it from the list. We don't mind adding something like this to huh, but it would be awesome to have a very compelling example that we can show off in the documentation.

Essentially when you remove an item from a list, users sometimes think your application is broken and that items they expect to be present are missing. It's better to be able to display the items, but make them unselectable / styled differently, and so forth.

An example to what david was pointing out would be:

Toppings:
> [ ] Lettuce
  [ ] Tomatoes
  [ ] Charm Sauce (sorry, we've run out!)
  [ ] Nutella

where we wan't to let the users know that the "Charm Sauce" option exists, but is just temporarily disabled in this case
