Changing the Reference Stablecoin of the APR Oracle on BNB Chain from BUSD to USDC

APR Oracle is the oracle that reads and calculates the 7-day average borrowing rate of the stablecoin on Venus. The borrowing rate is used as reference for the interest earned for BISHOP and the leveraged cost of ROOK. Currently, the stablecoin that the APR oracle uses is BUSD. With the current situation of BUSD, we propose to change the underlying stablecoin of the APR oracle from BUSD to USDC on the BNB Chain*.

*The stablecoin benchmark that APR oracle refers to on Ethereum is USDC and is not affected by this proposal.
