We have a nix CoreNLP definition: https://gitlab.iscpif.fr/gargantext/haskell-gargantext/blob/d362b468db3373972c5ef0ba24413c577355bdbd/nix/corenlp.nix

Thing is, this service is unrelated to gargantext in general.

My proposition is to move it away to a separate repo. One could the run it as a nix flake via nix run somerepo#startCoreNLP.

This will make it easier to just run corenlp on some machine, without the need to clone the whole of ggtx. Also, nix flake just for corenlp is faster to execute than, say, nix shell on our codebase.
