Replace Core modal by Bootstrap's one

mademo → made their first commit to this issue’s fork.

Usage :

href="[some-links]"
class="use-ajax"
data-dialog-type="modal"
data-dialog-options="{"dialogClasses":"modal-dialog-centered","dialogShowHeader":false}"
>
Open modal

Dialog options :

dialogClass => string
dialogShowHeader => boolean
dialogShowHeaderTitle => boolean
dialogStatic => boolean
dialogHeadingLevel => number

The change introduced here prevents Layout Builder to work.

 error occurred during the execution of the Ajax response: TypeError: Converting circular structure to JSON
    --> starting at object with constructor 'Window'
    --- property 'window' closes the circle
(

I will rollback.

Thanks to @nod_, MR 188 created that fixes one JS error. Now it works but, in Layout Builder, the offcanvas is replaced by the modal and also some other JS is not applied due to wrong execution order.

Needs deeper investigation.
