Error in Rollup section

In the Rollup section, a section is written:
For a complete setup example see this gist.
And the word /* see this gist. */
Link to a restricted page
This limitation causes problems in teaching. Please change to another type.
Link address:

The error I receive:

This secret gist has been disabled.
It appears your account may be based in a U.S.-sanctioned region. As a result, due to U.S. trade controls law restrictions, we are unable to provide private repository services and paid services for your account.

Ouvrez la section Rollup de la documentation sur les performances de React et examinez le gist de Rich Harris indiqué par le lien. Remplacez la référence au gist restreint par une alternative accessible, puis vérifiez que la section ne dirige plus les lecteurs vers la page désactivée.
