Description

Currently, there are lots of redundant intent and blank lines in highlight code blocks of docs. Such as

 in https://ci.apache.org/projects/flink/flink-docs-release-1.10/dev/batch/connectors.html.
The root cause is the redundant intent before {% highlight %} and {% endhighlight %}. We need to fix it to improve the reading experience.
