How do I add a data source for Google Page Speeed Insights about ds-data-registry

You only need to add a source definition. The org is Google so you can just use the existing Google org definition.
For the source it would be something like:
{
"id": "GOOGLE_PAGESPEED_INSIGHTS",
"name": "Google PageSpeed Insights",
"categories": ["TOOLS"],
"organization": "GOOGLE",
"iconUrl": "https://www.gstatic.com/images/icons/material/product/2x/pagespeed_64dp.png",
"sourceUrl": "https://developers.google.com/speed/docs/insights/about",
"dataVisibility": ["PRIVATE"]
}
