Remove qiskit-ibm-provider

Description

Removes qiskit-ibm-provider.

qiskit-ibm-provider is deprecated, and should be migrated to qiskit-ibm-runtime using the migration guide. The only use of qiskit-ibm-provider was in the docs, so this MR updates the docs to no longer use the deprecated module and drops the module from the mitiq[qiskit] requirements.

I let most of the examples send a circuit to IBM Quantum, and minor discrepancies in the code have been corrected from that as well.

This MR should also make dependabot MR #2306 unnecessary.

I had to add the requirement for qiskit-ibm-provider back in for Pennylane on Python 3.9. A TODO is included to remove it when Pennylane gets upgraded.

looks great!

[andre-a-alves]

After upgrading Pennylane, qiskit-ibm-provider~=0.11.0 still needs to remain a requirement in requirements-pennylane.txt for Python 3.9 until qiskit-ibm-runtime is upgraded. The comment was updated.
