Possible incorrect comment in `RollupAdminLogic`

[lucadonnoh]

I'm not sure this comment still holds and I'm a bit confused by it. To me it seems that new assertions always use the onchain confirmPeriodBlocks value.

nitro-contracts/src/rollup/RollupAdminLogic.sol

Line 312 in 780366a

// Normally, a new assertion is created using its prev's confirmPeriodBlocks

behavior is intended, comment seems to be off; thanks
