code-generator v0.31.0 incompatible with k8s.io/gengo/v2 v2.0.0-20240812201722-3b05ca7b6e59

[danielvegamyhre]

In my project k8s.io/gengo/v2 v2.0.0-20240812201722-3b05ca7b6e59 was bumped indirectly from updating k8s.io/api packages to v0.31.0, but now k8s.io/code-generator@v0.31.0 is failing, seemingly due to an incompatibility with genkgo/v2 package:
