NAKAMOTO_BLOCK_VERSION, unupgraded signers reject the block, because the unupgraded signers use the old version when trying to clone (and compare the block hash) of the proposed block.This change has the block validation endpoint clone the version of the proposed block to the local block, so that the block hash will match.
We may need more validation here about what a valid block version is - for example, I believe it needs to be <128, or it is treated as a shadow block. Thus, opening as a draft.
