etherpad.js does not get minified correctly with minify@5.2.0. Instead 
of the minified js, there is just 'Promise { <pending> }'. minify@5.1.1 
works correctly

Minify v6 requires node>=12

This will fix permissions issues : a Docker Volume mounted on a non-existing directory will be owned by root, but we run Etherpad as etherpad. As such we have no way of writing in the mounted directory

Cette fois ça devrait être bon !
