fix: agent log verbosity (#4054)

### Description

tbh I don't know why, but this makes all the logs we were previously
missing show up in e2e:
-
b99920ecca/rust/hyperlane-base/src/contract_sync/mod.rs (L155)
-
f68319f46e/rust/hyperlane-base/src/db/rocks/hyperlane_db.rs (L93)

### Drive-by changes

<!--
Are there any minor or drive-by changes also included?
-->

### Related issues

- Fixes https://github.com/hyperlane-xyz/hyperlane-monorepo/issues/3915

### Backward compatibility

<!--
Are these changes backward compatible? Are there any infrastructure
implications, e.g. changes that would prohibit deploying older commits
using this infra tooling?

Yes/No
-->

### Testing

E2E, by counting occurrences of the two logs linked above in relayer log
output. Before this change, those logs would be missing completely
