Remove Higher Order Components from Editors

In src/editors/...

1. Replace injectIntl with useIntl() -> https://github.com/openedx/frontend-app-authoring/issues/2280
2. Replace usage of connect with useSelector() and useDispatch() -> https://github.com/openedx/frontend-app-authoring/issues/2312
3. Update the code and tests to get rid of the Internal export pattern:
   Example of exporting (Component)Internal and Component = injectIntl(connect(...)) HOCs, then testing with the Internal one.

Once the HOCs (injectIntl, connect) are replaced with hooks, if it's necessary to mock redux state in tests, convert the tests to use initializeMocks from src/testUtils.tsx and pass in initialState to initializeMocks. Or use const { reduxStore } = initializeMocks(); and dispatch changes to the redux store.

Start by reviewing src/editors/ and the AnswerOption.jsx and AnswerOption.test.jsx examples, then read src/testUtils.tsx and the linked injectIntl and connect issues. Update the editor code and tests to use hooks and remove the Internal export pattern; use initializeMocks when tests need Redux state. Done means the listed HOCs and Internal exports are no longer needed.
