Description

Deprecates ip_addresses in resource and datasource mongodbatlas_project

Agustin Edit:
Verified that with the new plan modifier configured in ip_addresses the plan no longer show details associated to this attribute. This will avoid further client confusion until the attribute is removed completely.
