Fix for mypy errors

[woodsp-ibm]

Summary

CI has been failing in nightlies with mypy for couple of weeks (since the new mypy release)

_validate_keys() in the parent SparseLabelOp is defined as an abstract method! I removed these calls to super from the above

Details and comments

Stable branch would have the same issue but I did not label this for backporting as it includes a file (the majorana op) that is only present on main.

It seems the macos-latest images no longer have miniconda, As nature installs PSI4 under conda I switched for now back to macos-12. Also the macos-latest is now an ARM64 image not X86. While it seems both PSI4 and PySCF have ARM builds for now it seems simpler, to get CI running again (assuming this workaround does the trick), is just to go with the older image.

In other words to use macos-latest-large which would be the latest X86 image we would have to install miniconda in CI. I see CI uses some env var for CONDA and I do not know if this is created by the miniconda install or something that would need to be added. My goal was to get CI running and using the older image was simpler. With things running again changing up CI more to get the latest image running would be something that could be tried.
