Integrate Magnite aka Rubicon prebid partner

[deedeeh]

What does this change?

This PR adds Magnite, previously named Rubicon and that's the name used in docs, as a prebid bidder.

It includes:

• accountId, siteId and zoneId as they are required for integration. Please check Rubicon prebid docs for more info.
• Bump guardian/Prebid.js v8.52.0-1 for enabling Magnite bid adapter in our prebid.js fork Add Magnite as a bid adapter Prebid.js#149
• 1% AB test to receive data and check if they are in the correct key/value pairs. You can opt-in by adding #ab-PrebidMagnite=variant at the end of the url.

Other related PRs to this work:

• Frontend where AB test was added: Add Magnite 1% AB test and bump commercial v20.0.0 frontend#27329
• Frontend Add prebid Magnite commercial switch frontend#27335 for adding a switch. This one is already in PROD.

Here is the spreadsheet with all the info regarding ad-sizes, siteId and zoneId based on the different regions.

In CODE or PROD the commercial switch and the AB test switch must be on and you opt in the test and this is how you see rubicon as part of the prebid bidders in the commercial logger.

I was able to test the switch locally and in CODE but the AB test I tested it just in CODE as there is an issue with opt in client-side tests locally.

If you want to test locally checkout to this branch and comment out the logic related to && ab test so you can check the request and response for rubicon based on the commercial switch.

Note: Rubicon is the old bidder name but it's still used for the integration. Magnite is the current name so in the code you will see the two names as I am using rubicon when it is required for integration which is absolutely necessary for sending requests and getting responses and magnite is for anything else related to just our code. There will be an iteration/refactor in another PR to name everything in our codebase rubicon but we just need to get this out at the moment.

Why?

We would like to add magnite (rubicon) as a prebid bidder behind a 1% AB test.
