Sorry if the issue is short it is my first time creating an issue in this repo.

Thanks for the issue @TeenBiscuits!

This appears to be a bug in Astro/the Vercel adapter, being tracked here:

• @astrojs/sitemap excluded from final static output with Vercel adapter adapters#445
• [@astrojs/sitemap] Cannot add static source correctly using vercel on Astro 5 astro#12663

Don’t think we can fix it directly in Starlight, so I’d recommend subscribing to those issues to see when a fix is available.
