Pin compatible robosuite versions

Once `robosuite-dev` is updated, we should enter some compatible versions of `robosuite` e.g. using another branch of rs currently errors:

```
from robosuite.controllers import load_composite_controller_config
ImportError: cannot import name 'load_composite_controller_config' from 'robosuite.controllers' (/home/thankyou/autom/robosuite-dev/robosuite/controllers/__init__.py)
```
