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`.
## Examples
<.icon name="hero-cake" />
<.icon name="hero-cake-solid" />
<.icon name="hero-cake-mini" />
<.icon name="hero-bolt" class="bg-blue-500 w-10 h-10" />
