Previously, the logic that determined the field’s type would incorrectly
look at the contents of the array. For example, if the array contained
one or more objects, the field’s type would be resolved as Object rather
than Array.
This commit updates JsonFieldPath to record when a path explicitly
identifies an array so that the array itself is used to determine the
field’s type rather than its contents.
