Subject: [PATCH] progress.sh: handle more networks gracefully

Only OP-mainnet and sepolia are hardcoded. For other networks, use the
healthcheck RPC. If that is not set, give an informative message instead
of an error.

Refactor: move setting L2_URL down (it's not used earlier) and use a
case statement instead of multiple ifs.
