add a warning about LTS nearing EOL

it was a bit dodgey that we had no GUI notification of it. at the same
time we still don't know if there are even any users on the edition.
let's do the bare minimum. on LTS we'll now show a not localized message
about the EOL and point to the wiki (which has details and points to the
blog - the wiki has a nicer url which seems important since I can't make
intractable links in kdialog :shrug:)

advantage is that this didn't require actual engineering in comparison
to refitting distro-release-upgrader. also no useless work for
translators. we don't localize the blog or wiki so there'd be no point.

this currently has a "dont show again" option but we may want to drop
that as we get closer to the EOL to ensure people haven't forgotten
