doc: update Log4j2 configuration and gremlin-console guide

[VGalaxies]

When starting HugeGraphServer with the script or with IDEA, the log4j configuration file being read is not the same file, which may cause some confusion for new developers. Therefore, I have added this part of the content to clarify it.

The gremlin-console guide is for PR https://github.com/apache/incubator-hugegraph/pull/2231

EN doc will be synchronized later.

A small tips: we could paste the url directly if it belongs to the GitHub, and the UI will be more readable

Thanks, could also update the title of IDEA config doc, reduce the title to setup server in IDEA

Done.
