Should add constraints for versions 8.6.0, 8.6.1

### Solution to issue cannot be found in the documentation.

- [X] I checked the documentation.

### Issue

The jupyterlab extension that comes with this package requires jupyterlab >=3.6.3,<4.0.0 for ipyparallel versions 8.6.0 and 8.6.1, so this should be added as a constraint.

### Installed packages

### Environment info

Start by inspecting the ipyparallel feedstock recipe and its dependency constraints. Verify how version-specific metadata is expressed for ipyparallel 8.6.0 and 8.6.1; done means those versions require jupyterlab >=3.6.3,<4.0.0.
