Fix sonar scanner errors due to Java deprecated version (#265)

Due to end of support of the Java 11 (LTS) in Sonar, this PR updates the
version of Sonar Scanner to 5.0.1.3006. Additionally, the warnings
because of Node.js (version 16 to be unsupported in the near future) are
corrected. Actions `cache` is also updated to `v4`. The action for
`setup-java` was removed (we use now the JRE included in
`sonar-scanner`).

This closes #251
