Prop 405: Enable Superfluid Staking on OSMO/WBNB

On passing, this proposal would enable Superfluid Staking on the OSMO/WBNB (#840) 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/WBNB pool (#840).

If enabled at the current 50% discount rate, an additional ~167 thousand OSMO can be used to secure the network through staking.

This proposal comes after the bootstrapping period for WBNB implemented in Proposal 360 has ended.

WBNB was declared a major asset in Proposal 359 and arrives from Binance Smart Chain via the Axelar bridge.

## About WBNB
WBNB is the wrapped version of BNB and is the most liquid, volatile asset across Binance Smart Chain DeFi. BNB is used to pay for goods and services on Binance, settle transaction fees on Binance Smart Chain, participate in exclusive token sales and more.
