ruled.notifications remove mistaken code example line

[elig0n]

1. The second code example on ruled.notifications has what seems to be an extra unneeded line at the end:

naughty.connect_signal("request::display", function(n)
    naughty.layout.box { notification = n }
end)
    icon      = beautiful.awesome_icon,

In the source file it appears to come from a later, separate creation of a notification which doesn't appear in any doc.
I assume it is supposed to be hidden altogether.

2. The app_name string mdp appear several times in the file. I couldn't find such app, is it actually meant to be mpd ? Let me know and I will push a commit changing it

As a heads-up for future contributions: Small documentation fixes like you've been doing recently don't really warrant a separate, dedicated PR for each. Instead, by merging them like in for example #3529 (i.e. separate commits in a single PR) you can reduce the burden on reviewers.

for me small PRs are alright

and regarding mpd/mdp

the only mdp player i found is this one below, mb it meant to have a remote control widget for it 🙃
