 * * either adds or removes the image caption of a selected image (depending on whether the caption is present or not),
 * * removes the image caption if the selection is anchored in one.
 *
 * ```ts
 * // Toggle the presence of the caption.
 * editor.execute( 'toggleImageCaption' );

 *
 * **Note**: Upon executing this command, the selection will be set on the image if previously anchored in the caption element.
 *
 * **Note**: You can move the selection to the caption right away as it shows up upon executing this command by using
 * the `focusCaptionOnShow` option:
 *
 * ```ts
 * editor.execute( 'toggleImageCaption', { focusCaptionOnShow: true } );
