feat: reduce summary sent to only id and score

[kevinsamoei]

To reduce the processing work to be done for this data, it will be neat to just send what we need. This only affects what we send as part of extraData

This basically changes:

[
    { title: 'Performance', score: 1, id: 'performance', threshold: 0.5 },
    { title: 'Accessibility', score: 1, id: 'accessibility' },
    { title: 'Best Practices', score: 1, id: 'best-practices' },
    { title: 'SEO', score: 0.91, id: 'seo' },
    { title: 'PWA', score: 0.3, id: 'pwa' }
]

to

{   
  "performance": 100, "accessibility": 100, "best-practices": 100, "seo": 91,  "pwa": 30
