Fix of class namespacing on accessible modal

The namespacing generated by the data-modal-prefix-class attribute was not correct on close button and on another element inside this close button. It is fixed, so this namespacing can now do correctly its job: isolate each modal design without risking some collisions between them.

Demos have been updated: Demos of accessible modal Van11y.

The update has been published two days ago on Github/NPM (see Github repositery of Van11y modal).
