Remove unused optional requirements

With the removal of algorithms and opflow in Qiskit#11324, Qiskit#11111, and Qiskit#11086
several optional test dependencies are no longer used in the code base.
This commit removes them from requirements-optional.txt as several have
compatibility issues with Python 3.12 and are causing failures in the
nightly builds. Since they're no longer used we shouldn't bother
installing them anymore.
