    CI: include automatic Pull Request Labeler
    
    This adds GitHub CI action which makes use of 'Labeler', allowing
    automatic labeling of new PRs, based on the modified files paths.
    
    Below labels are supported and more can be added later:
    - 'target/*'
    - 'target/imagebuilder'
    - 'kernel'
    - 'core packages'
    - 'build/scripts/tools'
    - 'toolchain'
    - 'GitHub/CI'
    
    For more information:
