Privacy docs blocked by mandatory survey

Issue in ./help/ai-assistant/privacy.md

1. Google "Adobe AI assistant privacy policy"
2. Click Adobe's doc link to https://experienceleague.adobe.com/en/docs/experience-platform/ai-assistant/privacy,
3. (Issue) Get greeted with a non-closable popup survey that you must complete to view the doc behind it.

Start with ./help/ai-assistant/privacy.md and reproduce the linked Adobe privacy-policy page behavior. Determine what documentation change, if any, can address the mandatory survey barrier; done means the privacy information is reachable from the documented link without the reported access problem.
