PR #5204 incorrectly bumped op.clients.reth.client_version (op-reth image)
from v2.4.3 to v2.5.2. The us-docker.pkg.dev/oplabs-tools-artifacts/images/op-reth
registry has no v2.5.2 tag, causing deploy failures on chains like bob.sepolia
and soneium.mainnet that inherit the default op-reth client without override.
This reverts only the op-reth version change, keeping the intended top-level
reth (ghcr.io/paradigmxyz/reth) bump to v2.5.2 intact.
