This PR:

1. moves to the new toc definition within the myst.yml file (docs)
2. adds a team page with 2 example people cards. Note these will render properly/fully once deployed and will not look fully featured when previewing locally (yet), options available are 👇

  doc: 'An card for showing a person, for example, in a lab group',

    name: { type: String, doc: 'URL of the logo' },
