Improve Python SDK Release Process

[MOmarMiraj]

This PR will fix the current pain points of the release process of the Python SDK. This includes the following:

• Decoupling the building of wheels with the prep-release.sh script.
• Building the sdist in a more compatible way.
• Adding the ability to update the build number automatically through the scripts
• Create build_number.py inside the onepassword package to update the SDK_VERSION located in defaults.py
• Added support for Python 3.13(Tested with Docker on Linux) and refactored makefile to reduce redundancy.

Also with Python 3.13, the min macos version is 10.13 so added a check to ensure the correct version is being passed through depending on the python version.

Functionally tested and all is great! A few nits, as well as adding documentation, and this should be good to go.
