Support Astro's class:list attribute by default

[yuheiy]

In Astro, class:list={...} takes an array of class values.

<!-- This -->
<span class:list={[ 'hello goodbye', { world: true }, [ 'friend' ] ]} />
<!-- Becomes -->
<span class="hello goodbye world friend"></span>

Including class:list in the default tailwindCSS.classAttributes should make it more useful!
