## 📝 Summary

Update go-utils from v0.13.2 to v0.14.0:
flashbots/go-utils@v0.13.2...v0.14.0

1. rpcserver added`/livez` and `/readyz` handlers (readyz handler will
be implemented in a follow-up PR)
2. rpcserver using [goccy/go-json](https://github.com/goccy/go-json) for
faster JSON coding

## ✅ I have run these commands

* [x] `make lint`
* [x] `make test`
* [x] `go mod tidy`
