GitHub workflow: adopt distribution for actions/setup-java is deprecated

[gcatanese]

The adopt distribution for actions/setup-java is deprecated and will be removed in a future version. It is recommended to use temurin instead, which was the value used previously. Using a deprecated value could cause this action to fail in the future.

        distribution: 'temurin'
