Contradiction between documentation and annotation of the secure parameter of set_cookie()

[serhiy-storchaka]

The secure parameter of StreamResponse.set_cookie() is documented as bool, but is annotated as Optional[str].

What is right?

There is #3836
Since python/typeshed#3059 is fixed and new mypy is released we need to update set_cookie annotation.

[serhiy-storchaka]

#3836 does not touch the secure parameter.
