[stevennevins]

Summary

• switch check-super-root action test coverage from using op-supervisor to using supernode

Testing

• go test ./op-e2e/actions/interop -run TestSuperRootScript -count=1
• go build ./op-chain-ops/cmd/check-super-root

Metadata

Fixes #19177

Ah I think there's some confusion here - we want to keep the check-super-root script accepting multiple EL endpoints. That way you can use providers like Alchemy who won't provide supernode endpoints. I suspect we just need to switch the test over from using supervisor to verify against to supernode.

Makes sense, will adjust

LGTM. Just the one nit.

nit: I'd remove this. there are multiple places this method could cause the test to fail so we'd want to get the actual line, but t.Helper() will entirely exclude it from the stack trace.
