Dependency Problem: jupyter-client and rltk have conflicting requirements

`make requirements` fails due to a dependency conflict:

```
distributed 2022.11.1 requires tornado<6.2,>=6.0.3, but you have tornado 6.2 which is incompatible.
jupyter-client 7.4.7 requires tornado>=6.2, but you have tornado 6.1 which is incompatible.
```
