    Skip --explain-why for Python 3.10 in the deps summary job (#73449)
    
    Python 3.10 is losing support in more and more of our dependencies, so the
    constraints check has far more outdated packages to explain there, and each
    explanation costs a dependency resolution. That pushed the 3.10 job from
    ~18 to ~27 minutes on main. With 3.10 support being dropped in weeks, the
    explanations are not worth the CI time for that version.
