Invert API docs to point from NG to OG

[hynek]

People use and love the new APIs, we've got the Pont Neuf problem, let's invert the API docs.

• define()
  • https://attrs--1316.org.readthedocs.build/en/1316/api.html#attrs.define
  • https://attrs--1316.org.readthedocs.build/en/1316/api-attr.html#attr.s
• field()
  • https://attrs--1316.org.readthedocs.build/en/1316/api.html#attrs.field
  • https://attrs--1316.org.readthedocs.build/en/1316/api-attr.html#attr.ib

according to the specified attributes using attr.field or these

rather than

according to the specified attributes using attr.ib or these
