make start-operator not working correctly

[firatsertgoz]

make start-operator errors out with {"err":"open tests/keys/bls/1.bls.key.json: no such file or directory"} because the file structure changed

operator.anvil.yaml => ecdsa_private_key_store_path: tests/keys/ecdsa/1/key.json
bls_private_key_store_path: tests/keys/bls/1/key.json

seems like the correct paths

after fixing this I also ran into an issue:
