Git absolutely has distributed consensus. That's what merges are. That's the sense in which git is decentralized. What git does not have is distributed timestamping, which is necessary for a currency, but not version control. And which is why PoW et al were introduced for cryptocurrencies. However, that is not a fundamental property of a blockchain, though it is useful for some (but not all) of the applications of blockchains.
