Fix the SentinelType example on iterator_input_adapter

Browse Source 
The comment offered "a C++20 sentinel or counted_iterator" as examples of a
SentinelType, but std::counted_iterator is the IteratorType - the sentinel it
pairs with is std::default_sentinel_t. #5268 corrected the same wording in the
API documentation and left the code comment behind.
