* Improve npmplus credential retrieval and messaging
Enhanced the install script to attempt live log monitoring for credentials if not found initially, and updated the info message in npmplus.json to guide users to check docker logs if the credentials file is missing.
* Update npmplus.json
* Change updateable status to true in npmplus.json
