clarify array_contains function description
## What changes were proposed in this pull request?
The description in the comment for array_contains is vague/incomplete
(i.e., doesn't mention that it returns `null` if the array is `null`); this PR
fixes that.
## How was this patch tested?
No testing, since it merely changes a comment.
