Readonly helps out with TS's type guards and is also a good best practice. Specifically, readonly strings/numbers have their literal type instead of a generic `string` | `number` type, which can help catch dead code and some common programming mistakes

The underlying cause is the TextArea element is missing the readonly attribute.
This change applies the readonly attribute when the editor is created or the configuration changes to editor.readOnly === true.
