[Docs] Provide a description how to correctly use expect.configure with poll parameter

[viraxslot]

Hi team!
I see that the method expect.configure supports poll parameter.
I assume that I can create an alias for expect.poll command and write this:

export const pollExpect = expect.configure({
  poll: {
    timeout: 10_000,
  },
});

And in my test I use it like:

pollExpect(this.page.url()).toContain(urlToCheck);

I don't see any retries for the expect command in UI mode and I didn't use await keyword before pollExpect (it's not required) so I'm not sure that I understood it in a right way and it works OK.

Is it possible at all to do what I wanted?
Could you please update the docs and add an example if it is.

An example here is also appreciated :) Thanks for the awesome product!

@viraxslot sorry, this is a wrong type declaration! The poll option is not actually supported.
