[BUG] timeZone not implemented in CompositeDateHistogramAggregationSource

[yyj1219]

What is the bug?

timeZone not implemented in CompositeDateHistogramAggregationSource.

How can one reproduce the bug?

CompositeDateHistogramAggregationSource.of(cdha -> cdha
        .field("time")
        .fixedInterval(Time.of(t -> t.time("1h")))
        .timeZone("Asia/Seoul")
);

I expected timeZone(), but there is zoneId().
However, in OpenSearch 2.13, CompositeDateHistogramAggregationSource only supports time_zone and does not support zone_id.

What is the expected behavior?

Please add timeZone().

What is your host/environment?

OpenSearch 2.13 and OpenSearch Java Client 2.13
