    yocto: slides: improve PREFERRED_VERSION example
    
    Python 2 is really EOL now and it's not in any layer we use in the
    examples. Now there is only Python 3, the recipe is called "python3" but it
    implements one version only. For a more realistic example, switch to a
    package that currently has at least two versions. Unfortunately oe-core has
    no such recipe, thus pick one from meta-openembedded, which is nginx having
    the "stable" and "current" versions.
