Description

The current documentation does not provide detailed guidance when users attempt to use logback as the underlying logging framework. Since Flink only contains log4j dependency jars. The documentation says that if you want to switch to logback, you only need to exclude the log4j dependency, but it does not remind the user to add a dependency on the logback. I hope to add the following information:

• Remove the dependencies of log4j and slf4j-log4j in the lib folder;
• Where to download the logback-* jar
• Introduce logback-core/logback-classic/logback-access dependencies
