WIP: Qiskit 2 support

[MoritzWillmann]

A couple of changes are necessary to support Qiskit 2.0. I started to adapt some things but there are still things missing, also some things wee need to wait on.

• [x] qiskit_algorithms needs to be updated to support 2.0
• [x] BackendProperties doesn't seem to exist anymore and needs to be replaced accordingly in automatic_backend_selection
• [x] Mapomatic needs to support 2.0
• [ ] qiskit_machine_learning needs to support 2.0 or remove qiskit_machine_learning dep

[David-Kreplin]

Maybe a good chance to get rid of the qiskit_algorithms, which is only needed for fidelity quantum circuits. We have fast implementation for that for PennyLane and Qulacs, but not for Qiskit.

Mapomatic causes problems with Qiskit 2.0 since it also checks for BackendV1 that is depricated in Qiskit 2.0. I don't know, if they ever gonna update the Mapomatic Package, maybe we have to create a fix and hope someone will merge it and relase a new Mapomatic version.

Should be fixed now (https://github.com/qiskit-community/mapomatic/pull/77)
