Bug description

The documentation (https://swiperjs.com/swiper-api) states:

focusableElements	string	'input, select, option, textarea, button, video, label'	CSS selector for focusable elements. Swiping will be disabled on such elements if they are "focused"

But the relating vue prop focusable-elements is defined as a boolean.

Expected Behavior

If i set focusableElements via the focusable-elements prop, i expect that the focusable elements are set as a string, like stated in the docs.

Actual Behavior

[Vue warn]: Invalid prop: type check failed for prop "focusableElements". Expected Boolean, got String with value ".focusable". at [...]
