doc/conf/yaml: replace underscore with dashes

Use sed + regex to replace all occurrences of suricata.yaml terms that
used underscore for their up-to-date dash version.

Also search for such terms in the eve-log.yaml partials file, as that
is referenced in the configuration section.

commands used:

sed -i 's/\(^ *[a-z]*\)_\([a-z]*:\)/\1-\2/g'
sed -i 's/\(^ *[a-z]*\)_\([a-z]*\)_\([a-z]*:\)/\1-\2-\3/g'

Some other instances were found manually.
