fix(op-batcher): Fix PR #5186 Nits

[refcell]

Description

Fixes CLI-3678

PR #5186 was eagerly merged without proper review + fixes. This PR implements those requested minor nits relating to the op-batcher's MaxFrameSize validation.

Note: #5187 introduces a FrameV0OverHeadSize constant in the op-node rollup that can be used in place of the constant introduced here. As such, probably makes sense to wait for #5187 to be merged and rebase this pr.
