Make it possible to use page.keyboard.type('text') instead of page.ty…

Description

The selectors are sometimes cryptic and could break with adaptations in the DOM layout. Thus I use a custom selector (see other pull request). But the couldn't find a proper selector to use with typing in a field. Thus I made it possible that no selector is used and the function page.keyboard.type('text') is used. When testing I first click on the label and then type. So the duplicate selector isn't needed. I created an option to use the page.keyboard.type(). It is still defaulted to the page.type() function.
