fix broken link to ansible modules

[p-fruck]

Dear Jeff,

a minor issue I've just discovered is that your reference to the ansible module list (footnote 32) seems to be broken. Please replace https://docs.ansible.com/ansible/latest/modules/modules_by_category.html with e.g. https://docs.ansible.com/ansible/latest/collections/index_module.html

Edit: footnote 40, Ansible Docker Modules is also broken https://docs.ansible.com/ansible/latest/modules/list_of_cloud_modules.html#docker

Kind regards Philipp

Good catch; that was recently changed with the switch to collections.
