Update docs to reflect new OAuth config method

Code changes related to this request claim that API key authentication is deprecated by the MailChimp, but I couldn't find any information in this regard on either:

• https://mailchimp.com/developer/
• https://mailchimp.com/help/about-api-keys/
• https://mailchimp.com/developer/marketing/guides/quick-start/

Can you please link to the relevant documentation here .

Hi @RoSk0,

To be clear, this documentation is only referring to API key usage with this Drupal module. We deprecated API key usage now because, in the v3 release of this module, the API key connection will no longer be supported.

We are still working with the Mailchimp team on an update to their Mailchimp for Drupal documentation. That new documentation will note the deprecation of API keys with regard to the Mailchimp Drupal module. We will be sure to update the module description with a link to that documentation as soon as it is available.
