merge revision(s) c5475f42694eff35465c3332e0182c0611ca5918: [Backport #18748]

	Fix Range#cover? returning true for beginless ranges of different
	 types

	Previously `(2..).cover?("2"..)` was false, but
	`(..2).cover?(.."2")` was true.  This changes it so both are false,
	treating beginless ranges the same as endless ranges in regards to
	type checks.

	This also adds documentation to #cover? to describe behavior with
	beginless and endless ranges, testing each documentation example,
	which is how this bug was found.

	Fixes [Bug #18155]
