v1.3.0
Added support for dropdown menu (responsive) alignment: https://getbootstrap.com/docs/5.0/components/dropdowns/#menu-alignment
Here is how it works:
if one (or more) class(es) related to dropdown responsive alignment (for instance: dropdown-menu-sm-end) are detected inside the class list of the parent element, then they are copied into the class list of the .dropdown-menu element.
