copy button is not accessible

[Mantish]

Hi,
We're using the copy button feature which is really useful but is not accessible.

The problem is that they're not actual HTML buttons, so they can't be used by keyboard / screen reader users.

I think the easiest solution is to use a <button> element with the proper attributes like aria-label.
If that is not possible, a button role should be assigned, but also there needs to be a focus outline with keyboard, along with a tabindex of 0. In addition, it would need a hook or listener that looks for enter or spacebar to activate the copy item.
