Clarify "conjugate" method purpose

[boonware]

Summary

Implements #13322

Details and comments

Below I have listed each conjugate method as returned by this search query, together with the reason why or why not the doc string has been updated.

• AdjointMixin - Updated to reference only the complex conjugate, but I have not referenced the basis as this is an ABC. Precisely which basis depends on how the concrete class has implemented the abstract method.
• SparsePauliOp - This class has a to_matrix method, so reference to this basis is made.
• StabilizerState - The conjugate method returns the conjugate of the Clifford (operator) used to create the StabilizerState. As such, I have referenced the basis returned by the operator's to_matrix method.
• Unitary - This class has a to_matrix method, so reference to this basis is made.
• PauliList - Update the comment to reflect what is already in place for BasePauli.
• StateVector - This class has a data method, so reference to the basis of these vector components is made.
• DensityMatrix - This class has a data method, so reference to the basis of these vector components is made.
