Get Puppeteer Lighthouse information (a11y, performance, etc) from API

Is your feature request related to a problem? Please describe. You can currently output lots of detailed information related to matters such as accessibility, performance via console.log in Checkly browser JS checks, but it doesn't appear to the possible to retrieve similar information from the API request.

So in a browser check, I can script something like this following a Puppeteer invocation:

const snapshot = await page.accessibility.snapshot();
console.log(JSON.stringify(snapshot, null, 2));

...and see page accessibility information, but you seemingly can't retrieve similar from calling the API. Similarly, you can't invoke Lighthouse and get performance/accessibility information that way, as specifying const lighthouse = require('lighthouse'); at the top of a Puppeteer script produces an error:

Dec 29 00:25:57 - ERROR - UserScript TypeError: Cannot read property 'some' of undefined

Describe the solution you'd like It would be good if you could add additional page information to the JSON that's served from calling the API (or potentially calling another API endpoint).

Describe alternatives you've considered None so far (not sure of a way around API limitations).

Additional context Add any other context or screenshots about the feature request here.

@coderkind this is great feedback.

1. exposing the log data through the API is something we can do. Right now we store just an S3 filename in the DB which would not be useful as you can only access it through the API so we would need to expose that in some way.

2. We do not have the lighthouse lib incorporated in our runner infra yet, but we are working on something there. I noticed you found https://github.com/checkly/public-roadmap/issues/79 already. Please give it a 👍 so we can track it
