[ARFC] Add LUSD Arbitrum v3
Vote Result: YES
Rationale
Listing LUSD as a borrowable asset but not as a collateral (0% LTV) helps Aave diversify from the current dominance of centralised stablecoins such as USDC used for borrowing. It has proven to work well on Ethereum V2 and V3 and Optimism V3, so adding LUSD to Arbitrum V3 will not be a surprise. We therefore will vote YES in favour of this proposal.
