That's unfortunately a pip limitation. You can either disable build isolation so that the build requirements are using your current environment or you can use the PIP_CONSTRAINTS env var which will be passed through to the isolated build invocation allowing you to constrain the build requirements. In this case PyYAML did release a 6.0.1 version which contains an upper bound constraint on Cython.

After a year and a half with lots of alphas and betas, I don't think there is much cython could do, short of fixing PyYAML themselves.
