Type hints modernization

[woodsp-ibm]

Recently Qiskit Optimization updated its type hinting as per this PR qiskit-community/qiskit-optimization#676 It maybe something considering doing here too. The PR notes it used ruff and shows the config used.

We have been adopting the non-typing hinting for a while, but they're not at all consistent across submodules (eg Algorithms migrated parts still have the typing convention). So, it would be useful to harmonise this.

Do any Qiskit projects use instead Numpy dtype hinting? There was an old discussion about this and numpy.typing wasn't mature enough at the time, but should be now.
