Adopt molecule config JSON schema

We move official location for Molecule Config JSON Schema inside
molecule project itself. This will be followed by updates on
JSON Schema Store and on vscode-ansible extension, and removal
from ansible/schemas project. We already did the same with navigator
and lint project, as it makes the maintenance easier.
