docs not clear where es/config scripts are located

[pvgenuchten]

https://geonetwork-opensource.org/manuals/4.0.x/en/maintainer-guide/installing/installing-index.html#installing-index talks about a folder /es/config, however a deployed war does not have a folder /es, are these files anywhere available in the war, or only in the sources? in that case, better to reference the files on a public location (github?)
