Motivation for this change

Add a plugin for vim that does highlighting for typescript jsx.

example usage:

let
  myVim = pkgs.vim_configurable.customize {                                   
    name = "vim";                                                      
    vimrcConfig.vam.pluginDictionaries = [                                           
      { name = "vim-tsx"; }
    ];
  };
in
...

Then you can view a tsx file. This is an example file you could download to test.
