Adstxt 1.1 - Documentation (Early 2023)

What happens?

Ads.txt 1.1 introduces two new fields that aim at providing more transparency.

managerdomain: specifies the business domain of a primary or exclusive monetization partner of the publishers inventory
ownerdomain: specifies the business domain of the business entity that owns the domain

And also solves issues from 1.0 regarding the SC verification that relies on ads.txt + sellers.json + SCO (Supply Chain Object)
