Open Source Code Node Example - Deprecated scikit-learn functionality

[smlindauer]

In the hmeq_train.py code for the registery_py_model example, some users will find that the current Python code utilizes a scikit-learn method that has been deprecated. Specifically on line 66, the get_feature_names() method was deprecated in version 1.2 of scikit-learn.

I believe a simple solution for the code would be a try/except block as follows:

try:
    full_input_vars = dm_interval_input + list(class_ohe.get_feature_names())
except AttributeError:
    full_input_vars = dm_interval_input + list(class_ohe.get_feature_names_out())

Or to explicitly validate the scikit-learn version:

import sklearn
from distutils.version import StrictVersion
if sklearn.__version__ >= StrictVersion("1.2.0"):
    full_input_vars = dm_interval_input + list(class_ohe.get_feature_names_out())
else:
    full_input_vars = dm_interval_input + list(class_ohe.get_feature_names())

Thanks so much for the feedback @smlindauer - pushed your suggestion with try/except block to master.
