Typo on message passing between L2-L1 in Messenger spec

[miguelmtzinf]

I think the second and third sentences of this paragraph is incorrect.

https://github.com/ethereum-optimism/specs/blob/8efc7a3fe800367bb8f407ab4fe284570a18ebc9/specs/protocol/messengers.md?plain=1#L73-L80

It should read:

When going into L2 from L1, the user does not need to call relayMessage on L1 themselves. The user pays for L1 gas on L2 and the transaction is automatically pulled into L1 where it is executed on L2.
