Cross-site Scripting via Discourse-ai SharedAiConversation onebox in Discourse

Discourse AI is a Discourse plugin which provides a number of AI features. When sharing Discourse AI Bot conversations into posts, if the conversation had HTML entities those could leak into the Discourse application when a user visited a post with a onebox to said conversation. This issue has been addressed in commit `92f122c`. Users are advised to update. Users unable to update may remove all groups from `ai bot public sharing allowed groups` site setting.
