Gives neovim packages a extendConfiguration property, which is a method allowing users to extend this package's configurations with additional modules.
This allows users e.g. to derive .#nix config to generate their own config, assign that to global neovim package, and then in per-project's shell.nix, expand the config to include additional LSP modules or plugins, instead of having to redefine everything from neovimConfiguration.
