Update japicmp configuration

Update the japicmp reference version and wipe exclusions / enable API compatibility checks for @PublicEvolving APIs on the corresponding SNAPSHOT branch with the update_japicmp_configuration.sh script (see below).

For a new major release (x.y.0), run the same command also on the master branch for updating the japicmp reference version and removing out-dated exclusions in the japicmp configuration.

Make sure that all Maven artifacts are already pushed to Maven Central. Otherwise, there's a risk that CI fails due to missing reference artifacts.
