python dependency of 3.8+

[raj8github]

latest setuptools package in requirements has dependency of min 3.8+ which throws error when working on lower python version environments.

RuntimeError: Python 3.8 or later is required

as a workaround, we are using a constraints.txt file to force setuptools to 69.0.2 instead of pulling latest one.
