Failing to install; Colab notebook version

[The Colab notebook has an error](https://colab.research.google.com/github/deepmind/alphafold/blob/main/notebooks/AlphaFold.ipynb), likely due to a Python version mismatch.

When `pbar` reaches 17%, we get an error, here's the traceback:

LibMambaUnsatisfiableError: Encountered problems while solving:
- package conda-23.5.2-py310h06a4308_0 requires python >=3.10,<3.11.0a0, but none of the providers can be installed

Could not solve for environment specs
The following packages are incompatible
├─ conda 23.5.2 is installable with the potential options
│ ├─ conda 23.5.2 would require
│ │ └─ python >=3.10,<3.11.0a0 , which can be installed;
│ ├─ conda 23.5.2 would require
│ │ └─ python >=3.11,<3.12.0a0 , which can be installed;
│ ├─ conda 23.5.2 would require
│ │ └─ python >=3.8,<3.9.0a0 , which can be installed;
│ └─ conda 23.5.2 would require
│ └─ python >=3.9,<3.10.0a0 , which can be installed;
└─ pin-1 is not installable because it requires
└─ python 3.12.* , which conflicts with any installable versions previously reported.

Pins seem to be involved in the conflict. Currently pinned specs:
- python 3.12.* (labeled as 'pin-1')
