Point to newer version of Ansible in GAT documentation

[hexylena]

There are alot of links that point to version 2.9 of the Ansible doc website, in both tutorials

• I understand not pointing to /latest/, so that the link is more stable since /latest/ can change the subpath to the right, in the future
• But I think it would be good to update it to /9/ (Ansible changed version naming conventions, 9==2.17) since 2.9 is 5 years old
• I tried to it, but it was too time-consuming so I did not have the time
  • It is time-consuming because there are tens of links and about half are invalid if you just replace /2.9/ with /9/
  • I spent some time searching for the corresponding links in the new documentation, but I'm not good enough at Ansible for the moment to do that
