Changing the Utility Stablecoin for BISHOP & ROOK on BNB Chain from BUSD to USDC

This proposal is the second step of the previously approved proposal.

In addition to the APR oracle reference, Tranchess utilizes stablecoin, currently BUSD, to enhance liquidity for BISHOP and ROOK. Specifically, users can swap BISHOP/ROOK with BUSD or vice versa. There are three liquidity pools for the three BISHOP tokens on BNB Chain, all in the form of BISHOP-BUSD. With the imminent support for BUSD wavering, we propose to change the stablecoin used on Tranchess from BUSD to USDC on BNB Chain*.

*The stablecoin we use on Ethereum is USDC and is not affected by this proposal.
