vimPlugins: assign original name to pname

instead of the normalized_name.

there is no need to rename the plugin ?! and it can upset packages for instance packer.nvim generates a config/nvim/plugin/packer_compiled.lua that does vim.api.nvim_command('packadd packer.nvim') which doesnt work on nixpkgs since the "packer.nvim" folder is renamed to "packer-nvim
