Subject: [PATCH] programs.neovim: expose generatedConfigViml (#2213)

Expose the generated viml config, this has 2 advantages:
1/ user can choose to write the generated config to a file of its choice
2/ the user can prepend/append to the config before writing it

    xdg.configFile."nvim/init.vim".text = ''
	" prepend some config
	${programs.neovim.generatedConfigViml}
	" append some config
    '';

NOTE: this was already possible with
xdg.configFile."nvim/init.vim" = mkMerge [
  (mkBefore {
    text = ''
      " prepend some config
    '';
  })
  (mkAfter {
    text = ''
      " append some config
    '';
  })
]
