fix(formbuilder): validation criteria for Select question types DEV-1283 (#6469)

### 📣 Summary

Fix UI for the validation criteria of question types Select One and
Select Many.

### 💭 Notes

It looks like a 10+ year old bug. But that can't be right, right?

### 👀 Preview steps

1. ℹ️ in formbuilder for question type Select One, go to "settings" and
then "validation criteria"
2. click "add a condition"
3. 🔴 [on main] UI starts to misbehave, error in console
4. 🟢 [on PR] it works
