enum.ref support in requires compatibility with interactive mode

[emilecaron]

Description

The new feature works well, and we now get proper enum validation from the enum.ref in a requires.
However when using in interactive mode, we still get a free input instead of the very nice select list that we have for static enums.
I'm not really sure if this classifies as feature request or bug, but i feel something is probably missing here.

Hey, good catch.
Indeed enum.ref could use the interactive prompter
