gh-154320: Fix swapped __defaults__/__kwdefaults__ in annotationlib docs (#154321)

The bullet list under "Creating a custom callable annotate function"
had the attribute names reversed: positional defaults are __defaults__
(a tuple) and keyword defaults are __kwdefaults__ (a dict). The example
code below was already correct.

Fixes #154320
