Use bytecode instead of byteCode in all cases

$ curl https://compiler.aepps.com/api | jq . | grep bytecode -i
    "ByteCode": { <-- as two words
        "bytecode": {} <-- as a single word

In comparison with "source code", seems correct to write "bytecode" as a single word, https://en.wikipedia.org/wiki/Bytecode 🤷‍♀️
