    make_dev.9: Fix mda_cr typo + polish
    
    The make_dev_args_init structure example said mda_cred, however the
    correct form is mda_cr according to the reporter and my git grep.
    A new document description has been contributed by jhb. While here,
    fix grammar and trivial typos (spacing, colons before examples,
    trailing delimiter) and spdx.
    
    MFC after:              3 days
    Reported by:            jhb (much polish and document description)
    Reported by:            Evgenii Ivanov on Community Discord
