Module imports in makeNixvimWithModule

[mbrea-c]

As far as I can tell the imports attribute is getting ignored when using makeNixVimWithModule. Being able to import submodules would be pretty useful for modularizing my nixvim config.

Since there's already an extend function on standalone configurations, how hard do you think it'd be to implement module imports?
Would you accept a PR for it?

Thanks!

My bad, I had a typo in my import path. Seems like module imports work as expected
