query object is not outputing the TIMEOUT argument in case of 0 ( 0 means unlimited for RediSearch TIMEOUT parameter )

[filipecosta90]

Version: 4.6.0 or any above 4.4.1 given the timeout parameter was introduced there (https://github.com/redis/redis-py/releases/tag/v4.4.1)

Description: I was checking why we where not seeing the timeout parameter on a RediSearch query monitor with timeout(0) which means unlimited execution time on RediSearch.
Given the following:

q = (
            Query(
                f"{prefilter_condition}=>[KNN $K @vector $vec_param EF_RUNTIME $EF AS vector_score]"
            )
            .sort_by("vector_score", asc=False)
            .paging(0, top)
            .return_fields("vector_score")
            .dialect(2)
            .timeout(0)
        )

notice that on the output of q.get_args() we're missing the TIMEOUT 0:

['*=>[KNN $K @vector $vec_param EF_RUNTIME $EF AS vector_score]', 'RETURN', 1, 'vector_score', 'SORTBY', 'vector_score', 'DESC', 'DIALECT', 2, 'LIMIT', 0, 100]

checking the code we see that the integer 0 will be interpreted as False on the condition https://github.com/redis/redis-py/blob/master/redis/commands/search/query.py#L197

if self._timeout:
   args += ["TIMEOUT", self._timeout]
