Update wordpress itself

Wordpress is installed using APT, so apt upgrades will update it. (so we'll only get really new versions when going to Buster. Maybe we should use the WP tarball instead of the packaged WP)

Languages, themes and plugins are automatically updated. See skwotfarm:/etc/cron.daily/update_wp_components

Update parts

Note: there is now a script update_wp_components that can be launched to run all wp components updates

FIXME: Even when it says "Success: Translations up-to-date" the wordpress Dashboard still says there is a translation update available.
