Add auto <meta name="theme-color"> injection on HTML.

Lighthouse is showing me the following error:

Address bar does not match brand colors
Failures: No `<meta name="theme-color">` tag found.

More info about this here.

My config:

new WebpackPwaManifest({
   name: 'My Progressive Web App',
   short_name: 'MyPWA',
   description: 'My awesome Progressive Web App!',
   start_url: '/',
   background_color: '#00b2ff',
   theme_color: '#00b2ff',
   'theme-color': '#00b2ff',
   icons: [{
      src: path.resolve(__dirname, '../../assets/js.png'),
      sizes: [96, 128, 192, 256, 384, 512],
      destination: 'icons'
   }]
})
