[feature] Automerge withdrawn EIPs

[lightclient]

Intuitively, it feels like if the author of an EIP elects to withdraw the EIP, it shouldn't need editor approval.

See here for example:
ethereum/EIPs#4189

Yes. If an author approves a withdraw, it should auto-merge. I think it should also auto-merge if an editor approves, that way if we receive approval in an incorrect form (like an author just giving a thumbs up or a PR comment) we can push things through for them without having to override.

btw I won't add this to my workload until it's a [feature] / concensus

There isn't likely to be anyone else who chimes in on the issue. @pooja may have some thoughts, but none of the other editors actively participate in these kinds of discussions.
