removeListener -> off

[ob1]

Puppeteer deprecated the removeListener some time ago in favor of off and in latest version they removed removeListener entirely

Do you think this will require a major version increment?

My personal view is "no".
I think it's better for the world to get this by default rather than having to bump a major.
Users with very old puppeteer might break, and then will have a choice - either upgrade puppeteer (which they should) or use a fixed version of the older version of this testkit.
