This patch release introduces a major fix and some minor fixes.

Major fix: searchable attributes database bug

Some searchable fields were removed from the searchable databases when they were removed from the filterableAttributes setting.
This made them unsearchable, although they were still precise in the searchableAttributes setting.

Fixed by @ManyTheFish in #5660

Minor fixes

• Fix chat route missing base URL and Mistral error handling by @Kerollmops in #5665
• Various fixes to embedding regeneration by @dureuill in #5668
