* feat(types): improve typing of `.evaluate()` This is the start of the work to take the types from the `@types/puppeteer` repository and port them into our repo so we can ship our built-in types out the box. This change types the `evaluate` function properly. It takes a generic type which is the type of the function you're passing, and the arguments and the return that you get back from the `evaluate` call are typed correctly.
