logback.xml Incorrect configuration

[heihei180]

Describe the bug
this file example/src/main/resources/logback.xml config the log file path is error.

line 23 and line 26.
like this:

        <file>/Users/xiweng.yy/logs/nacos/perf.log</file>
        
        <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
            <fileNamePattern>/Users/xiweng.yy/logs/nacos/perf.log.%i</fileNamePattern>
            <maxIndex>${JM.LOG.RETAIN.COUNT:-7}</maxIndex>
        </rollingPolicy>

i think should use

        <file>${user.home}/logs/nacos/perf.log</file>
        
        <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
            <fileNamePattern>${user.home}/logs/nacos/perf.log.%i</fileNamePattern>
            <maxIndex>${JM.LOG.RETAIN.COUNT:-7}</maxIndex>
        </rollingPolicy>
