Use Maven 4.0.0-rc-4

[FanJups]

The isssue #275 updated pom.xml files with new features of Maven 4.
Now, the build is failing because GitHub Actions use Maven version < 4 .

To solve this problem, we must update our GitHub WorkFlow to use Maven 4.
In that case, we will use 4.0.0-rc-4 -> https://archive.apache.org/dist/maven/maven-4/4.0.0-rc-4/
