Fix python version.

[zzhlogin]

Issue #, if available:

1. change tox.ini py3{7,8,9,10,11} to 3.{7,8,9,10,11} so that the workflow can run unit test.
2. change project Dokerfile to use python 3.10, because we are using opentelemetry-exporter-otlp-proto-grpc, it use grpcio as dependencies. It seems like grpc has a strict dependency on the OS / Python version. Also mentioned in Docker build template in upstream.
   When we use python 3.11 to build the docker file, we receive "Cannot import name 'cygrpc' from 'grpc._cython'" in EKS auto-instrumentation injection. As https://github.com/MicrosoftDocs/azure-docs/blob/main/articles/azure-functions/recover-python-functions.md#the-python-interpre[…]tions-python-worker suggested, Azure Functions support python 3.6 - 3.9, but while testing, 3.10 also worked. So change to 3.10 here.
3. As we change the python version for Dockerfile we also change main_build and release_build workflow to align with Dock build.
