Switch to AI Integration - ECA from the deprecated AI ECA sub module

Problem/Motivation

We had #3543089: Enable AI ECA integration module by default in Varbase AI

But the AI sub module for ECA was moved as a standalone module

AI Integration - ECA
This module replaces the previous attempts of integrating AI and ECA. There has been the standalone AI - ECA module and the AI ECA integration sub module in the main AI module. Both of them are obsolete and all of their functionality is now available in this module.

ai_eca   11001 - Checks to ensure a smooth  migration from AI sub module to external   module.

Proposed resolution

Add "drupal/ai_integration_eca ~1 in the composer.josn file.
Enable the AI Integration - ECA
