Use latest compatible grpcio-tools version and unlock support for Python 3.11

[discordianfish]

Currently blocked to 1.48.2 because of TF 2.x limitation of protobuf < 3.20 (and TF is currently used in Ray RL Lib). This also limit python version to 3.11 as it requires a newer grpcio version (above 1.48)

Files affected:

• Engine Docker File
• diambra-engine python package build-pip-package
• GH actions limited to python 3.10

To sum this up:

• ray-rllib needs tensorflow 2.x
• tensorflow 2.x needs protobuf (<3.20,>=3.9.2)

$ for v in 2.11.0 2.10.1 2.10.0 2.9.3 2.9.2 2.9.1 2.8.4; do echo "$v: $(curl -s https://pypi.org/pypi/tensorflow/$v/json | jq .info.requires_dist|grep protobuf)"; done
2.11.0:   "protobuf (<3.20,>=3.9.2)",
2.10.1:   "protobuf (<3.20,>=3.9.2)",
2.10.0:   "protobuf (<3.20,>=3.9.2)",
2.9.3:   "protobuf (<3.20,>=3.9.2)",
2.9.2:   "protobuf (<3.20,>=3.9.2)",
2.9.1:   "protobuf (<3.20,>=3.9.2)",
2.8.4:   "protobuf (<3.20,>=3.9.2)",

• Since there can be only one version installed, we need to depend on protobuf (<3.20,>=3.9.2) as well
• grpcio-tools generates the diambra-arena-engine code assuming a specific protobuf version
• grpcio-tools depends on that protobuf version:

$ for v in 1.51.1 1.50.0 1.49.1 1.48.2; do echo "$v: $(curl -s https://pypi.org/pypi/grpcio-tools/$v/json | jq .info.requires_dist|grep protobuf)"; done
1.51.1:   "protobuf (<5.0dev,>=4.21.6)",
1.50.0:   "protobuf (<5.0dev,>=4.21.6)",
1.49.1:   "protobuf (<5.0dev,>=4.21.3)",
1.48.2:   "protobuf (<4.0dev,>=3.12.0)",

Therefor we need to:

1. Generate diambra-arena-engine using a grpcio-tools version that generate code for a version matching protobuf (<3.20,>=3.9.2), e.g 1.48.2
2. Use that version's dependency (protobuf (<4.0dev,>=3.12.0) in our setup.py

That will allow users to install ray-rllib where pip dep resolver should install protobuf <3.20,>=3.9.2 while allowing users not depending on ray/tf2 to also install <=3.12.0 and >=3.20.
