Update versions of python used due to end of life

[Zahed-Riyaz]

The Dockerfiles and other dependencies in the repository currently rely on Python versions (3.7.5, 3.8.10) that are now end-of-life or nearing end-of-life in security status.
Using outdated Python versions can pose security risks.
Python 3.7 reached end-of-life on June 27, 2023.
Python 3.8 reached end-of-life on October 14, 2024 (depending on the exact release schedule).

Proposed Solution : To Upgrade python versions

Move the Dockerfiles (and any relevant scripts) to a currently supported Python version (e.g. 3.10, or 3.11, depending on project compatibility).

Update Dependencies:

Review and update any libraries or dependencies that may be incompatible with newer Python versions.

Testing & CI:

Ensure all tests pass locally and in CI pipelines.
Update any references in documentation (README, CONTRIBUTING, etc.) to reflect the new Python versions.

Open Questions / Considerations :

• Are there known compatibility concerns with upgrading to newer Python versions?
• Do maintainers have a preferred target version of Python (e.g., 3.9 vs. 3.10)?
• Is there a planned timeline or roadmap for dropping support for Python 3.7/3.8?

I've been running things with python 3.9.21. Everything falls apart starting at 3.10
