Documentation: netconsole: Separate literal code blocks for full and short netcat command name versions

Both full and short (abbreviated) command name versions of netcat
example are combined in single literal code block due to 'or::'
paragraph being indented one more space than the preceding paragraph
(before the short version example).

Unindent it to separate the versions.
