Warn users if `cmdstan` version does not match expected version #2490

My environment had a version mismatch in cmdstan: the expected version was 2.31.0, but the installed version was 2.32.1 (see #2489). This led to extremely poor forecasting results and lot of time spent trying to tune the model with no improvement. Prophet should warn or error when the cmdstan version does not match the version from the compiled Prophet model.

In python, the cmdstan version can be retrieved from cmdstanpy.show_versions()

If it is true that this issue is affecting the prediction results, I think it should definitely be improved.
