[MRG] Change ExtraTreesRegressor criterion from 'mse' to 'squared_error'

[jotoak]

Changes are made to be compatible with scikit-learn version 1.0. Version bump of both scipy and numpy is also done. This pull request also requires #1148

It worked for me to use this patch. I simply used @jotoak repository as source of the package (requirements.txt file of my project):

scikit-optimize @ git+https://github.com/jotoak/scikit-optimize.git@master

For reference, the error I had occurred after the initialization steps and was:

sklearn.utils._param_validation.InvalidParameterError: The 'criterion' parameter of ExtraTreesRegressor must be a str among {'poisson', 'absolute_error', 'squared_error', 'friedman_mse'}. Got 'mse' instead.

I am running this on an Apple Silicon M2, and so I couldn't get back to an old version of sklearn.
