VMP22 - Update BTC/USDT Perpetual quote name and liquidity monitoring triggering ratio

This is a proposal to modify the liquidityMonitoringParamaters.triggeringRatio to 0.1 so that it is aligned with the ETH Perp as per recommendations of the Vega team. The quote name is also changed to USD to match the underlying reference rate from the oracle. This can be modified again once a USDT oracle is available.

The triggering ratio is being set to 0.1 to reduce the chances of liquidity auctions, while the quote name is being set to USD since the underlying oracle data quotes the price of BTC against USD."

Looks good to me though it may be worth keeping the initial time on the time triggers in line with the market creation proposal to avoid shifting the time widnows (and uindented consequences this may bring).

Good point, I will make sure the initial timestamps are aligned before finalising the proposal. Thank you!
