Add info about initiative and release differences to project page
<!--Please search existing work items before filing to avoid duplicates.-->
<!--Also check open feature request work items to avoid duplicating existing proposals.-->
## Summary
The project page could do a better job explaining the difference between the minor releases (1.2, 1.3, 1.4) and leading people to information about the overall initiative.
## Problem
There is a lot of information in the project description, but nothing that helps developers understand which minor version to choose or what to expect when upgrading minor or major versions. This is standard info on many Drupal project pages and would be helpful to add here.
Some of this info exists in blog posts and on the initiative page, but there is no path to those pages from the project description.
Having a link to the initiative and summary of differences between the versions would help developers and others who come to Drupal AI through direct links and searches that land them on the project/module page.
## Proposed solution _(optional)_
Add a link to the AI Initiative https://www.drupal.org/about/ai/initiatives somewhere near the very top (maybe under Try the Drupal AI Demo, could add a section Learn about the Drupal AI Initiative?)
Add a brief section "Upgrading and Release Notes" that gives a one line summary of each minor and major release branch, any special upgrade considerations, or links to blog posts that explain the differences.
## Workaround _(optional)_
Ask in Slack, know someone who knows.
## Affected modules / components _(optional)_
