Support for Python 3.10 syntax

Hi, what is the timeline for Python 3.10 syntax support?

This is a big Python release that has several syntax improvements:

For example this valid python 3.10 code results in apython:ParsingError with SonarCloud:

def py310(pattern: str):
    match pattern.split('/'):
        case ('bar', 'foo'):
            print('bar first')
        case ('foo', 'bar'):
            print('foo first')
        case _:
            print('no match')

I understand that all these changes might not be readily supported in SonarCloud but a timeline will help us schedule our own upgrade to Python 3.10.

Thank you.
