Apply button pattern to all buttons on project

Buttons patterns are apply to Accordion-item, alert, carousel, modal, navbar and off-canvas.

Hi,

What do you think about this MR?

I think there are relevant usages. For the case where there is a button but without btn and other classes, maybe not needed to call the pattern for that.

There are nice ideas to avoid code duplication too like in navbar, I think.

Maybe also looking at the details--accordion, fieldset and some commerce template, to be able to call matching patterns directly?
