Indicate that docs/simulate/virtual_engine_interface.ipynb depends on unreleased features (#7528)

Closes #7517

Follow up to #7500, which listed
this notebook in `SKIP_NOTEBOOKS` in order to get past CI breakages due
to the fact that the notebook tests install the fully-released version
of Cirq. Once the parameter renaming is released, this can be removed.
