Delete a categorization rule

Deletes one categorization rule of a Books instance by ID, so it no longer categorizes transactions from now on. Ledgers, i.e. general ledger (GL) accounts, that the rule already applied to transactions stay in place; deleting a rule does not un-categorize anything. Only rules that getBooksCategorizationRules returns can be deleted; any other ID, including the organization's other automation rules that Books doesn't show, is a 404. To find rule IDs, use getBooksCategorizationRules. Returns no content on success, and 404 otherwise.
