[Enhancement] Add document for Debugging RocketMQ in Idea

[joeCarf]

Before Creating the Enhancement Request

• I have confirmed that this should be classified as an enhancement rather than a bug/feature.

Summary

So far, it seems that there is no document for developers to start and debug rocketmq in Idea, which is necessary for contributors or anyone who wants to read source code.

Motivation

The idea is very common in Java programming, adding a document for debugging rocketmq locally is necessary.
