ChoiceInput choices property cannot be set to an expression

[lauren-mills]

Describe the bug

I have a dynamically generated list of choices for a ChoiceInput, but in the latest build I cannot provide an expression as the value of the choices property for my prompt. I only see the option to provide "simple choices", "structured choices", and "unknown" but for unknown there is no input box.

I also tried explicitly setting the choices property to an expression in the json viewer, but then I get a UI error. I also see an error when I run the bot (this worked in previous versions, so not sure if the updated ChoiceInput schema is the culprit)

            {
              "$kind": "Microsoft.ChoiceInput",
              "$designer": {
                "id": "J7Pz46"
              },
              "defaultLocale": "en-us",
              "disabled": false,
              "maxTurnCount": 3,
              "alwaysPrompt": false,
              "allowInterruptions": false,
              "choiceOptions": {
                "includeNumbers": true,
                "inlineOrMore": ", or ",
                "inlineOr": " or "
              },
              "property": "dialog.choice",
              "choices": "=dialog.choiceList"
            },

Also, I have updated my dynamic list to use the following format based on what the SDK expects:
