log@2.3.0

02481501 (#2377 by @3lpsy) Add a is_skip_logger flag to the Log Plugin Builder struct, a skip_logger() method to the Builder, and logic to avoid acquiring (creating) a logger and attaching it to the global logger. Since acquire_logger is pub, a LoggerNotInitialized is added and returned if it’s called when the is_skip_looger flag is set. Overall, this feature permits a user to avoid calling attach_logger which can only be called once in a program’s lifetime and allows the user to control the logger returned from logger(). Additionally, it also will allow users to generate multiple Tauri Mock apps in test suites that run and parallel and have the log plugin attached (assuming they use skip_logger()).
