Build-wheel jobs are failing

[Opt-Mucca]

cibuildwheel just pushed a new major version. The jobs are automatically downloading the new version (3.0.0) and our pyproject.toml is now longer valid.

The (proper) fix:

• They've deprecated one of the parameters we were using. I tried replacing it with what the documentation said was the new replacement (enable = ["cpython-freethreading"]), however that seems to have wider consequences. Specifically, it does not work off the bat with 32 bit.

The easier temporary fix if this needs to be handled quickly:

• Add a version requirement of <3 when pip installing cibuildwheel in the GitHub actions for now. That should be a hacky 15 line change that would kick the problem down the road.
