[FLINK-30009] OperatorCoordinator.start()'s JavaDoc mismatches its behavior

Description

The following description lies in the JavaDoc of OperatorCoordinator.start().

This method is called once at the beginning, before any other methods.

This description is incorrect because the method resetToCheckpoint() can be invoked before start(). For example, RecreateOnResetOperatorCoordinator.DeferrableCoordinator.resetAndStart() uses these methods in this way. Thus the JavaDoc of OperatorCoordinator's methods should be modified to match this behavior.
