Prop 536: Enable Superfluid Staking on OSMO/ARB

On passing, this proposal would enable Superfluid Staking on the OSMO/ARB (#1011) pool on Osmosis.
## Details
Superfluid proposals ask whether governance trusts in the stability and security of the chain sufficiently to allow their tokens to have an influence on Osmosis governance.

This proposal would enable Superfluid Staking in the OSMO/ARB pool (#1011).

If enabled at the current 25% discount rate, an additional 142 thousand OSMO can be used to secure the network through staking.
## About Arbitrum
Arbitrum is an Ethereum L2, optimistic rollup. As an Ethereum scaling protocol, it makes transactions significantly faster and cheaper. The team at Offchain Labs launched its flagship chain, Arbitrum One, in May of 2021, and the Arbitrum ecosystem has quickly become a hub for DeFi. A separate AnyTrust chain, Arbitrum Nova was introduced in July of 2022 which is optimized for low-cost transactions.

The ARB token airdrop on March 23, 2023 decentralized governance of both Arbitrum chains and their underlying protocols. As part of this initial decentralization effort, 113 million ARB tokens were distributed to DAOs building apps on Arbitrum via and airdrop to their respective treasury addresses.

ARB is currently provided on Osmosis via the Axelar bridge.
