Now that we switched to cabal as our primary build system with stack being the "platform" out of which we derive a cabal.project, the use of package.yaml is misleading, because it forces us to go via the extra step of running hpack and we are running stack2cabal with the --no-run-hpack option, so the content of package.yaml would be ignored anyway, and generally speaking it makes sense for us to just treat gargantext.cabal as the single source of truth, as we are moving towards Cabal.

I'm going to remove the package.yaml from the project altogether.
