* Valid values for OTEL_PHP_LOG_DESTINATION: error_log, stdout, stderr, none, psr3, default

* (default = psr-3 if LoggerHolder::set called, otherwise error_log

* Note that PSR-3 logging will only work if a PSR-3 logger is registered in OpenTelemetry\API\LoggerHolder::set()

* If no PSR-3 logger is available, it will fall back to using error_log.
