Make it works with .mjs files

[levvsha]

Great approach with compiling of mjs files for modern browsers is described in this article. I faced with a problem when I specify output.filename in a webpack configuration file as a file with .mjs extension:

output: {
  filename: 'main.mjs',
  path: path.resolve(__dirname, 'public'),
},

Webpack is sucessfully compile all files but html-webpack-plugin does not append the generated files to the template (htmlWebpackPlugin.files.js is an empty array). It would be great to make it works with .mjs output files by default or with some flag in the configuration.
Expected result: the string <script type="module" src="main.mjs"></script> is appended in the template.

@levvsha I don't sure that closing this issue now is good idea, because PR is not merged yet
