[EW] Restore version via prompt does not work

Prompt: "restore /index to its original content"

Response: "I can see the version history but unfortunately I'm not able to directly read and restore a specific older version"

Source: https://jira.corp.adobe.com/browse/SITES-45764

Start by reproducing the prompt “restore /index to its original content” and compare the response with the version history behavior described in the issue. Trace the restore flow from that prompt; done means the original content of /index is restored instead of only reporting that restoration is unavailable.
