Problem/Motivation

The following error appears when trying to enable Customize headings and save the text format:

AssertionError: Schema errors: Array ( [editor.editor.id_does_not_matter:settings.plugins.ckeditor5_heading.customize] => variable type is integer but applied schema class is Drupal\Core\TypedData\Plugin\DataType\BooleanData ) in assert() (line 729 of core/modules/ckeditor5/src/Plugin/Editor/CKEditor5.php).

It only seems to happen when using Drupal 9.

Proposed resolution

Cast to a boolean in Heading::submitConfigurationForm().
