[docs] [issue18313] In itertools recipes repeatfunc() defines a non-keyword argument as keyword

This would require you to provide at least two elements, whereas now it's possible to pass just the function (e.g. repeatfunc(random.random)).

The problem with the current signature is that you are "forced" to specify the "times" (positionally) whenever you want to pass args to the function -- even if you want an endless repetition (i.e. times=None).
