spike: use astro to render kestra.io docs

[elevatebart]

• The starlight theme does not allow us to target content/docs for the source of docs. -> we will not be using starlight
• All assets have to move from /public to /src/assets to be optimized
• The sidebar menu needs to be reimplemented
• Optimization: Should we do ISR? IE cache pages on cloudflare, avoid deploying when only content has changed and simply invalidate cache on the content pages we have modified.
• for Vue components integration in md we can use mdx but for static content we should simply re-implement the rendering in a remark plugin (specially if it's only the alert and collapse components)
• We should also replace all the ::div with actual <div> to avoid confusion.
• Migrate all NuxtImg and NuxtLink to imported KsImg and KsLink
