Update clover-maven-plugin version to 4.4.1, some important changes are as follows:
- the license key is no longer required to run Clover
- the Atlassian brand and logos were removed to avoid any trademark violations
- the 'org.openclover.*' groupId is used for artifacts
The license key is no longer required is the key factor to do this update. So the developer can run and get the code coverage easier.
