Fixes #18448: ensure all buttons have a type.
Since patternfly tables CSS requires the table actions header to be in a
form it is important for all buttons to have type="button" as the
default type for html buttons is submit which thereby "submits" causing
the ng-click event of the first button in the form to be executed.
