Follow-up to #35810. Doing the same for AggregateError.errors. Since we never serialize them on the Server in prod, we don't need to consider deserializing them in prod on the Client. Also acts as defense-in-depth.

Follow-up to #35810. Doing the same for AggregateError.errors. Since we never serialize them on the Server in prod, we don't need to consider deserializing them in prod on the Client. Also acts as defense-in-depth.

Follow-up to #35810. Doing the same for AggregateError.errors. Since we never serialize them on the Server in prod, we don't need to consider deserializing them in prod on the Client. Also acts as defense-in-depth.

Follow-up to #35810. Doing the same for AggregateError.errors. Since we never serialize them on the Server in prod, we don't need to consider deserializing them in prod on the Client. Also acts as defense-in-depth.
