    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:

    (cherry picked from commit 4f42566d47999c392c8ea41dc27215b43ed9ee40)
