Fix setuptools missing dependency (python 3.12)

[gwenblum]

32 (python 3.12 images recently removed setuptools which is required by steelscript container build)

@gwenblum Hi! Whilst this solution will fix the failures, it's actually not fixing the root cause, which is that the steelscript package isn't correctly declaring it's dependencies. Specifically, the package has a run-time dependency on pkg_resources (part of setuptools) here: https://github.com/riverbed/steelscript/blob/5cf26666fd7025152d4c5a374e11b8258c17dcf8/steelscript/__init__.py#L1

...but doesn't list setuptools in install_requires in setup.py: https://github.com/riverbed/steelscript/blob/5cf26666fd7025152d4c5a374e11b8258c17dcf8/setup.py#L55-L58

If anyone were to install the package directly (and not use the Docker images), the issue would still exist unless install_requires were updated instead.

Thanks, you are right adding setuptools in the install_requires is much better. Let's fix that.
