Use dot -V to check if graphviz is installed

[nagra-gs]

Hi 👋 ,

Our laptops are behind a firewall and we don't have access to homebrew. We can however install graphviz via Nix.

Can we change the method in GraphService.swift - isGraphVizInstalled() to use dot -V to check if graphviz is installed? Thanks.

Best,
Kam

Make sense! feel free to open a PR for it 🚀

I've never contributed to a repo on Github before 😅, do I need write access to Tuist to do it? Thanks.
