What this PR does / why we need it:
Fix bug in JSON path parser where an error occurs when a range is empty.
The problem was that if the range contained no results, the position of the parser loop was not advanced to the end node, so when it reached the end node in the loop it seemed like there was no open range.
The fix is to make sure even if there are not results in the range, that it still advances to the end node as if it had processed something.
(BTW, this whole file seems sort of fragile and hard to conceptualize due to all the counters that are used across functions. Seems like there should be some opportunity to improve this, but that is for another time)
Which issue(s) this PR fixes:
Fixes #95882
