bug: neovim plugin lua dependencies are sometimes not discovered

[craigfurman]

Are you following the right branch?

• My Nixpkgs and Home Manager versions are in sync

Is there an existing issue for this?

• I have searched the existing issues

Issue description

Since 3c71ea7, luaRocks dependencies of neovim plugins (e.g. telescope-nvim's dependency on plenary-nvim) do not result in that dependency being placed in $XDG_DATA_HOME/nvim/site/pack/hm/start.

A workaround for this is to force a vim plugin dependency by applying this override in an overlay: https://github.com/NixOS/nixpkgs/pull/492746/changes

thanks for providing a workaround. I had this problem in mind but it was not tested in HM then I forgot about it.
The way lua dependencies in neovim work need some refactoring. I am trying to go through several neovim related issues that have been unattended for years so please bear with this workaround until a fix land in nixpkgs.
