Concentration fails to compile with PyYaml = 6.0.0

[vedang]

I tried installing concentration using pipx (pipx install concentration) as well as compiling it (poetry install). In both cases, it failed with the following error:

Installing dependencies from lock file

Package operations: 13 installs, 1 update, 0 removals

  - Downgrading pyyaml (6.0.1 -> 6.0): Failed

  ChefBuildError

  Backend subprocess exited when trying to invoke get_requires_for_build_wheel

Note: This error originates from the build backend, and is likely not a problem with poetry but with pyyaml (6.0) not supporting P
EP 517 builds. You can verify this by running 'pip wheel --no-cache-dir --use-pep517 "pyyaml (==6.0)"'.

On Googling, I found the same stack-trace in https://github.com/python-poetry/poetry/issues/8287, and also an associated fix: Upgrading PyYaml to 6.0.1

I did that using poetry add pyyaml, which fixed the problem.

This PR contains the changes to the lock file due to the poetry add pyyaml command.
