Generic/CamelCapsFunctionName: remove two incorrect code comments

This sniff only listens to `T_FUNCTION`. It does not listen to
`T_FN` or `T_CLOSURE`. So the removed code comments are incorrect. The if
conditions are still valid to bail early when live coding, but it does not
ever apply to closures or arrow functions.
