Fix Validator spreadsheet

[skywalkerdude]

Was using a legacy API: https://www.googleapis.com/auth/spreadsheets.currentonly

Need to fix script to add explicit auth scopes: https://developers.google.com/apps-script/concepts/scopes#setting_explicit_scopes

[skywalkerdude]

Need to add:

  "oauthScopes": [
      "https://www.googleapis.com/auth/spreadsheets.currentonly", 
      "https://www.googleapis.com/auth/script.external_request"
  ],
