[8.x] Change whereStartsWith, DocBlock to reflect that array is suppo…

…rted (#39370)

* Change DocBlock to reflect that array is supported

whereStartsWith, whereDoesntStartWith, thatStartWith DocBlocks says it only accepts a string, but an array is accepted as it's being passed to Str::startsWith($haystack, $needles) which accepts an array too.

* Changed docBlock for php 7 compat

* change use ($string) -> use ($needles)
