KYLIN-4864 Fix .travis.yml syntax

[martin-g]

Proposed changes

The commented line about # mvn sonar:sonar -e -Dsonar.host.url=https://sonarcloud.io ... has broken the YAML and because of this TravisCI didn't execute any jobs.
I wasn't able to find a way to preserve the commented line and fix the syntax, so I removed the line. Later it could be get from Git history to re-enable Sonar.

While here I've improved few more things:

• install OpenJDK and unzip for both AMD64 and ARM64. This way it uses latest JDK 8 (1.8.0_292) for both CPU architectures
• fix more YAML warnings

Thanks @martin-g !

@hit-lacus Welcome!

Where could I find the source code of the website ? I'd like to fix https://kylin.apache.org/development/#ci-and-code-analysis. Currently it points to Jenkins, i.e. error 404.

[martin-g]

I think I've found it!
http://svn-master.apache.org/repos/asf/kylin/site/ - is this the one ?

The source code of apache kylin is located at https://github.com/apache/kylin/document . https://github.com/apache/kylin/tree/document is the official website , not the svn .

[hit-lacus]

Following two files should be what you want :

• https://github.com/apache/kylin/blob/document/website/_dev/index.md
• https://github.com/apache/kylin/blob/document/website/_dev/index.cn.md
