Only HTML output in SSG mode

If nuxt content will be ever comparable with Astro then is require to adopt static rendering with NuxtIsland component. Right now it isn't and we get non-optimized js on static build.
This will heavily improve all pages with documentation. It should be note that right now NuxtIsland is in experimental phase and now is great time to align changes so components can be wrapped dynamically when detected that there isn't any dynamic changed (or add option to manually attribute setup script).

This can be future to have all new way to interact like dynamic components or CPG (Component Pages Generation that is dynamic to environment or other context provided by WebRTC). Generation in cache directory can cut generation time in half and more

Probably this is in work but no info anywhere other than Atinux (thanks!):

Hi @XenBG

This is a bit tricky in term of performance drawbacks but this is something we can think of leveraging the Island components.
