[FLINK-37665]: Simplify DoubleMaximum.clone() Implementation

[atu-sharm]

What is the purpose of the change

The purpose of this change is to simplify the implementation of the clone() method in the DoubleMaximum class by leveraging the existing constructor DoubleMaximum(double value) instead of manually setting the max field

Brief change log:

The current implementation of the clone() method in the DoubleMaximum class uses the default constructor and manually sets the max field:

// Some comments here
@OverRide
public DoubleMaximum clone() {
DoubleMaximum clone = new DoubleMaximum();
clone.max = this.max;
return clone;
}
This can be simplified by directly using the existing constructor DoubleMaximum(double value) to initialize the cloned object. The proposed change is:

@OverRide
public DoubleMaximum clone() {
return new DoubleMaximum(this.max);
}

Verifying this change:

This change is a trivial rework / code cleanup without any test coverage.
