In mud verify, don't give me an Etherscan URL when irrelevant

[qbzzt]

I verified a contract on Blockscout:

qbzzt@Oris-MacBook-Pro contracts % pnpm mud verify --worldAddress 0x40cc08060341a8449d0906fb5daf3cc1bf996b05 --rpc $ETH_RPC_URL --verifier blockscout --verifier-url https://eth-holesky.blockscout.com/api

Note: MUD is currently unable to verify store, world, and world-modules contracts with blockscout. We are planning to expand support in a future version.

Submitted contract for verification:
	Response: `OK`

Why do I get the etherscan URL? The blockscout one, https://eth-holesky.blockscout.com/address/0xB9A596A532AD582f80E6f88Aa4ec48c492749A11 , in a lot more useful.
