MDEV-27972: Unexpected behavior with negative zero (-0) in

Browse Source 
JSON Path

Analysis: When we have '-' followed by 0, then the state is
changed to JE_SYN, meaning syntax error.
Fix: Change the state to PS_INT instead, because we are
reading '0' next (integer) and it is not a syntax error.
