With the removal of Pulse in Qiskit 2.0, support for serializing ``ScheduleBlock`` programs
via the :func:`qiskit.qpy.dump` function has been removed. Users can still load payloads
containing pulse gates using the :func:`qiskit.qpy.load` function, however those will be
treated as opaque custom instructions. Loading ``ScheduleBlock`` payloads is not supported
anymore and will result with a :class:`.QpyError` exception.
