docs(sfc-script-setup): <script setup> cannot contain ES module exports

[dargmuesli]

Commit 7ab3991 fixed issue #1678 by introducing an export to the interface Props. This export clashes with a specification in the same file, I think, which states:

A normal <script> may be needed in cases where we need to: [...] Declaring named exports.

This can seemingly lead to a new issue with [plugin:vite:vue] [@vue/compiler-sfc]: <script setup> cannot contain ES module exports. If you are using a previous version of <script setup>, please consult the updated RFC at https://github.com/vuejs/rfcs/pull/227.

What's the proper way to resolve this issue? What am I missing?
