DataForm: if a field of type text declare elements, render it as a SelectControl in edit

[oandregal]

Part of #59745
Follow-up to #63983

What?

For text fields that have elements, this PR renders a SelectControl with the elements — like the integer type does.

How?

• Render as SelectControl if field has elements. 04039f8
• Updates the DataForm storybook to include a field with elements whose type is text.

Testing Instructions

Visit the storybook (npm install && npm run storybook:dev), go to the DataForm component and verify it has a status field rendered as a SelectControl.

I counted on implementing this when adding the status field to DataForm but the component for status is more complex — so better to have this one in before we forget adding it.
