Standardize Code and Update pyproject.toml to Python 3.11

Description:

We need to standardize our codebase to ensure compatibility with Python 3.11. This involves updating the pyproject.toml file and making any necessary code adjustments to align with Python 3.11 standards.

Tasks:

• Change the Python version to 3.11 in the pyproject.toml file.
• Ensure all dependencies are compatible with Python 3.11.
• Review the codebase for any deprecated or incompatible features with Python 3.11.
• Deploy to DEV.
• Run end-to-end test suite in a Python 3.11 environment.
• Include a note in the changelog regarding the update to Python 3.11.
