Updates your attachments whitelist. This defines which file types are allowed as attachments.
Provide a list of file extensions (e.g., ["PDF", "TXT", "JPG", "DOC", "DOCX"]).
Note: This endpoint uses PUT (full replacement), not PATCH (partial update).
All file types must be specified; any types not included will be removed from the whitelist.
