neovim: make the wrapper more evolvable
Now that we have structured attributes enabled, it's easier than ever to access the wrapper config from itself. Let's expose the 'plugins' derivations instead of the final 'packpathDir' with which one can't do much. TLDR: the neovim wrapper accepts a list of neovim derivations in `plugins` instead of the symlinkJoin of plugins in `packpathDir`. With exposed plugins, one could tweak the current wrapper with more plugins, e.g. neovim.withPlugins([fugitive]).withPlugins([plenary]) . we could also add a boolean to autoadd the plugins passthru.initLua, better handle the dependencies (runtime programs, python deps).
