Support for python 3.11+

[mdantonio]

Hi, is python 3.11+ officially supported?
setup.py reports >=3.6 but I'm having errors with python 3.11

cairo-lang/src/starkware/cairo/lang/setup.py

Line 20 in 0e4dab8

python_requires=">=3.6",

ValueError: mutable default <class 'starkware.cairo.lang.instances.CpuInstanceDef'> for field cpu_instance_def is not allowed: use default_factory

coming from

cairo-lang/src/starkware/cairo/lang/instances.py

Line 79 in 0e4dab8

cpu_instance_def: CpuInstanceDef = field(default=CpuInstanceDef())

Starknet-py 0.20 introduced support for python 3.12, so I was trying to upgrade our current python environment (from python 3.9).
With python 3.10 I haven't observed issues, but this check could be limited, and based on some specific use cases.
For maximum compatibility, what version of python do you suggest to use?

Python 3.10 seems to work well in 99% of cases, but I think the main supported and tested version is 3.9.

3.11 would be great indeed as it brings a free 25% increase just by upgrading , and better typing
