Returning empty IEnumerable should include skipping the same number of elements source has, not just less than it.

### Type of issue

Typo

### Description

"If source contains fewer than count elements, an empty IEnumerable is returned." should be changed to "If source contains fewer than or equal to count elements, an empty IEnumerable is returned". Because if source had count number of elements and count of them are skipped, the remaining is empty IEnumerable.
