  Renders a [Hero Icon](https://heroicons.com).

  Hero icons come in three styles – outline, solid, and mini.
  By default, the outline style is used, but solid an mini may
  be applied by using the `-solid` and `-mini` suffix.

  You can customize the size and colors of the icons by setting
  width, height, and background color classes.

  Icons are extracted from your `priv/hero_icons` directory and bundled
  within your compiled app.css by the plugin in your `assets/tailwind.config.js`.
