Pages Router’s custom Document

If your site is using Pages router, the Makeswift custom Document export has been moved from @makeswift/runtime/next to @makeswift/runtime/next/document. To migrate, adjust the custom Document import in src/pages/_document.ts as follows:

- export { Document as default } from '@makeswift/runtime/next'
+ export { Document as default } from '@makeswift/runtime/next/document'

Here is the link to the official release notes.
