Cancun error with BLOBBASEFEE

[holiman]

Previously reported via https://gist.github.com/holiman/a833485f09445201787f88f0fdb55133 , re nethtest 1.26.0-unstable+4d1bebe48c74c9c42197ba6de514f9de96d9642f

Still happening in nethtest 1.27.0-unstable+927f1d4a92ea58472634fbd23209b952c7420ff8

---

It seems like nethermind suddenly forgot (at least in statetests) that blobbasefee is a Cancun opcode. Very odd.
