Description

Currently, if a user runs the "Add missing patterns" code action on this code:

case some_value.optional_field {}

They would get something like:

case some_value.optional_field {
  option.Some(_) -> todo
  option.None -> todo
}

Which is correct, but doesn't account for the fact that they need to import the gleam/option module. It would be helpful to detect this and automatically import gleam/option in this case.
