Review Comment:
We can call this from `validateValues`, but then I won't be able to take
your other suggestion to mention `inter.broker.protocol.version` in the error
message. This one gets called when the KRaft broker discovers a new
metadata.version via a new feature record. Would you prefer we consolidate the
checks, or keep mention of `inter.broker.protocol.version` when it makes sense?
I lean towards leaving them both, so it's helpful for the operator, and the
duplication cost should go away in 4.0.
