[Resources] Service WS - Custom and root URLs
The custom URL lacks the specification of the layer name.
ex.:
https://download.data.grandlyon.com/ws/grandlyon/all.json
instead of
https://download.data.grandlyon.com/ws/grandlyon/cad_cadastre.caddetailsurfacique/all.json
Moreover, the correct root URL is as follows: https://download.data.grandlyon.com/ws/grandlyon/all.json
