Allow adding textarea in the code editor

See #3507929-2: Allow adding image properties in the code editor → for how the BE piece can be unblocked there, with one difference: here we need to set

type: string, $ref: json-schema-definitions://experience_builder.module/textarea

This issue needs to get a BE MR that is 99% identical to that in ✨ Allow adding image properties in the code editor Active : same new validation constraint, just a different set of enabled choices. Let's first land that one, which then leaves only a tiny additional *.schema.yml + test coverage only change to be done over here.

Blocker's in.

FYI: XB's OpenAPI validation may disallow and we forgot about an integration test for this — see #3507929-19: [Back-end] Allow adding "image" props in the code component editor → .

🤩

I think reusing the existing ui/src/components/form/components/TextArea.tsx would prepare us better for CKEditor 5 support in the future? See https://git.drupalcode.org/project/experience_builder/-/merge_requests/7....

Fantastic work! 👏🏻

Just noting here that as things are, code component authors will need to add white-space: pre; (or whitespace-pre with Tailwind) until we introduce using the nl2br() function in the backend before passing the prop values. (@effulgentsia looked up the backend parts.)
