fix: Fix ci build doc

[hiohiohio]

Context:

• ci build docs is failing

Changes:

• update ci.yaml to use python 3.11
• add multiple python versions for test
• ignore protected_namespaces of PyDantic as temp solution to fix #339

Additional considerations:

• sorry, my formatter does a little of format changing

We may exclude 3.12-dev for now?
