Remove redundant V1Job Clone() method

[Andre-Lx-Costa]

The method Clone() is redundant as there is DeepClone() with the same functionality.

So the method clone() bellow can be removed:

        /// Clones a job object.
        /// </summary>
        /// <param name="job">V1Job to clone.</param>
        /// <returns>New V1Job object.</returns>
        public static V1Job Clone(this V1Job job) =>
            JsonSerializer.Deserialize<V1Job>(JsonSerializer.Serialize(job));
