seo: Google search returns a link that goes to 4.0 docs

[serjikibm]

A google search for ibm granite docs, lists the link https://www.ibm.com/granite/docs/models/granite, which sends the user to the 4.0 page, vs https://www.ibm.com/granite/docs  which sends the user to the 4.1 page

Would be nice to maybe make https://www.ibm.com/granite/docs/models/granite go to 4.1 page, while the current 4.0 page (https://www.ibm.com/granite/docs/models/granite) to become https://www.ibm.com/granite/docs/models/granite4-0
