Suppress GCC warning in TreeEnsembleAggregator (microsoft#22062)

### Description
When building with GCC 14.2.1, I got the following warning:

onnxruntime/core/providers/cpu/ml/tree_ensemble_aggregator.h:329:59:
error: template-id not allowed for constructor in C++20
[-Werror=template-id-cdtor]

Remove template parameters from the constructor: The constructor
TreeAggregatorMax<InputType, ThresholdType, OutputType> has been
simplified to TreeAggregatorMax, because the compiler already knows the
template parameters from the class definition.

### Motivation and Context
Fix the build issue
