Thank you ! I can't do a full review tonight (for me, CET), but if you want to make changes in between, I'll copy what is stated at the beginning of this file:

# NOTE: This file is auto-generated from 'scripts/docgen.mjs'
# Do not make edits to it directly, they will be overwritten.
# Instead, change this file: https://github.com/withastro/astro/blob/main/packages/astro/src/types/public/config.ts
# Translators, please remove this note and the <DontEditWarning/> component. 

This means this file is read-only and the content comes from the JSDoc in https://github.com/ryechus/astro/blob/c1f212b47585f7c5869e47cd13ffc4ebfce12b08/packages/astro/src/types/public/config.ts#L1203-L1226

Currently, the two do not match. And since JSDoc serves as public documentation, you will likely want something that falls somewhere between the two descriptions.

If this is a config only change (I haven't checked in details the implementation), you might not need a docs PR and the JSDoc is enough. If it affects more pages (e.g. https://docs.astro.build/en/guides/server-islands/), we'll need a docs PR for those pages, but you can omit configuration-reference.mdx (unless this is a 1:1 match and you want to check the rendering, then it's okay)!

Thank you! I'll try to fix this up before you get online tomorrow!
