Release 4.2.3

Instead of the mStable MTA/WETH Staking BPT (mBPT) being held in the Staking Token BPT (stkBPT) contract, it is deposited into the new Balancer mBPT Gauge Deposit (mBPT-gauge).

MCCP 21: Stake BPT staked in mStable into Balancer Staking contract has details on why the change was done.

See Pull Request #350 for the detailed contract changes.
