The pyyaml dependency might need to be updated to 6.0.1

[FabijanC]

Currently the requirements specify 6.0:

cairo-lang/scripts/requirements.txt

Line 48 in cc86dfc

PyYAML==6.0

I noticed this while building a Docker image for starknet-devnet: CI/CD log - error at the bottom

People on SO advised updating Pyyaml to 6.0.1 (version released on 18 July: history) which is what I did in the starknet-devnet repository and this really resolved the issue, but I'm guessing it should preferably be addressed at the cairo-lang project level.
