Comparing the Fermionic operator computed with qiskit-nature and qiskit-alt.

The fermionic operators are equal, and the coefficients in the PauliSumOp may be different in order but it remains the same operator.

The VQE is run with the same ansatz, optimizer, and VQE function from qiskit-nature.

The output ground state energy is still different.

Eventually, we don't have to push this notebook to the main branch.
