Update broken Slack link again (#1339)

* Fix type of HookedTransformerConfig.device (#1230)

* Fix type of HookedTransformerConfig.device

This is typed as `Optional[str]` but sometimes returns `torch.device`.
Updated the code to just return the `str` instead of wrapping with a
device.

I'm not confident that every function which takes a device will
always be passed a string, so I didn't change functions like
warn_if_mps.

Found while working on #1219

* more cleanup

* 3.0 CI Bugs (#1261)

* Fixing `utils` imports

* skip gated notebooks on PR from forks

* Updating notebooks

* Ensure LLaMA only runs when HF_TOKEN is available
