Description

The logger.warning_once function, if given two arguments, will interpret the first argument as a format string and the second as its arguments. To prevent this unintended string formatting, we use string literal concatenation to pass a single string argument. See python docs and other code.
Any way this message also need a change here because the current verison is 4.47.1 now.
