Wheels for torch 2.0

## Instructions To Reproduce the 🐛 Bug:
1. Full runnable code or full changes you made:

Running the Colab demo for Detic - https://colab.research.google.com/drive/1QtTW9-ukX2HKZGvt0QvVGqjuqEykoZKI#scrollTo=S7MpTaZ0YNTb

results with an error as pytorch 2.0 is not part of the pre-build wheels - https://detectron2.readthedocs.io/en/latest/tutorials/install.html#install-pre-built-detectron2-linux-only

3. __Full logs__ or other relevant observations:
```
torch: 2.0 ; cuda: cu118
Looking in indexes: https://pypi.org/simple, https://us-python.pkg.dev/colab-wheels/public/simple/
Looking in links: https://dl.fbaipublicfiles.com/detectron2/wheels/cu118/torch2.0/index.html
ERROR: Could not find a version that satisfies the requirement detectron2 (from versions: none)
ERROR: No matching distribution found for detectron2
```

Start with the linked Detic Colab demo and the Detectron2 installation page, then inspect the pre-built wheel index for the reported torch 2.0 and cu118 combination. Reproduce the pip failure and determine the wheel-generation or publishing entry point involved. Done means the documented installation succeeds for that combination and the demo can install Detectron2.
