The paste content buttons now have the type "button" set
to not falsely behave as submit buttons, which is the default
if no type is defined.

See: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/button#attr-type

Note: In this case the regular submit event is prevented by
JavaScript which leads to no actual functional change here.
