Fix the install_pyspec_test CI check

[jtraglia]

It looks like this CI test was accidentally broken in this PR. We just need to update the cache version.

• Update python to 3.12.4 #3880

I'm not sure why Rust (via ethpandaops/circleci-python-rust:latest) is necessary. I don't think it should be. If there's an issue, I'm hoping the CI check will tell me which package needs it. (edit: Oh it's py_arkworks_bls12381, that makes sense. But this is a mistake. It only provides pre-built wheels up to python 3.11, we can fix this).

Also, there's no need to call make preinstallation as preinstallation is a dependency of install_test:

consensus-specs/Makefile

Lines 107 to 115 in ad91a83

	# check the setup tool requirements
	preinstallation:
	python3 -m venv venv && \
	. venv/bin/activate && \
	python3 -m pip install -r requirements_preinstallation.txt
	install_test: preinstallation
	. venv/bin/activate && \
	python3 -m pip install -e .[lint,test]

[hwwhww]

@parithosh could you help confirm it?

For reference, I pinged @kevaundray and asked him to publish pre-built wheels for Python 3.12 to py_arkworks. You can see these here: https://pypi.org/project/py-arkworks-bls12381/#files

Ah amazing! I only added rust to get around the py_arkworks_bls12381. If that has been fixed, i agree we should switch back to the official python image.
