contracts-bedrock: mainnet deploy config fee vault recipients

Update the fee vault recipients to their final value
before the upgrade. The value can be changed through an
L2 contract upgrade. The values were previously set to
a hardhat test account. We never need to recycle the ether
back to the test accounts because they already have so
much ether that it is fine to set it to its final value.
