Add support for Python 3.11

[woodsp-ibm]

Summary

Following Python 3.11 support being added to the other application repos, in particular Qiskit Optimization which this uses, by qiskit-community/qiskit-optimization#481, the support for 3.11 is now added here to Qiskit Finance.

Details and comments

This initial step updates the set of files, such that they linted, passed tests etc locally under 3.11. I want first to check that this all works across the present set of OS's and Python versions and then I will add Python 3.11 jobs to CI.

• Include 3.11 in workflows
• Reno

Although this is ready to be merged into main - given the branch protection rules are updated accordingly - I would want to backport this to stable so Finance can support 3.11 when Optimization, on which Finance is dependent, does. This is therefore needs optimization releasing first since stable is run against the released packages not the dev branch, Hence I marked it on hold until the Optimization is next released.
