[FAB-3087] Fix peer/core.yaml misleading comments

The following comments in the core.yaml are misleading and confusing to users.
    # The Address this Peer will bind to for providing services --> This is simply not true
    address: 0.0.0.0:7051
    # Whether the Peer should programmatically determine the address to bind to.
    # This case is useful for docker containers. ---> This is not accurate
    addressAutoDetect: false

I fixed them to reflect the real meaning behind them
