Description

This proposal is to upgrade the default version of Python to 3.10 for Blender 3.10.

Blender itself has supported Python 3.10 for some time now, I've been using it since 3.10 was released.
As far as I can see most of the work needed for upgrading python is updating pre-compiled binaries.

There are various improvements & optimizations since 3.9 (see release notes) 3.10 offers better error messages, giving useful suggestions about how to resolve the error.

Since 3.10 has been out for a while I think it's a good time to switch from 3.9.
This also makes moving to 3.11 less disruptive (which is shaping up to have some good overall performance gains).

I would be all up for it... but this would 'break' our following of the VFX platform, which for its 2022 version still requires python 3.9 (https://vfxplatform.com/).
