Use correct wheel depending on Python version

[Pelochus]

For ezrknn-toolkit2, it is necessary to use an exact Python version depending on package that will be installed. Default Python version may vary from OS to OS. Solution proposed:

• Install latest compatible (as of writing, Python 3.11)
• Check version and install corresponding one
