docs: // SetTextTemplate will set the current text template for all loggers on the
  // default collection with names that match a provided regular expression. If
  // the regular expression is nil, then all loggers match. Note that not every
  // handler is guaranteed to support text templates and a text template will
  // only apply to text-oriented and unstructured handlers.
