Change groupId of java artifacts

[hohwille]

Current groupIds:
http://repo1.maven.org/maven2/com/devonfw/modules/
http://repo1.maven.org/maven2/com/devonfw/starter/
http://repo1.maven.org/maven2/com/devonfw/microservices/

Expected groupIds:
http://repo1.maven.org/maven2/com/devonfw/java/modules/
http://repo1.maven.org/maven2/com/devonfw/java/starters/

Also microservices seem to be java and should change their groupId.
