fix: bump crdify to fix bugs and regressions
regression fixes: 1. correctly handle processing of properties that are OpenAPI items 2. allow enums to have values added. bug fix: crdify's served version validator was updated to actually compare the old CRD with the new CRD so that any issues identified in the old CRD do not continue to be reported when performing comparisons between served versions of the new CRD. This effectively allows issues in the served version validations to be acknowledged once when they are introduced, but then those issues are essentially grandfathered in such that they do not have to be acknowledged again in the future. This issue was actually identified in a case where an operator upgrade was stopped by the CRD upgrade check despite there being no changes whatsoever to the CRD. The "old" and "new" CRDs contained the exact same issues, but since crdify was looking exclusively at the "new" CRD, it found those issues and reported them.
