Replace deprecated ANSIBLE_COLLECTIONS_PATHS env var

Ansible 2.16 deprecated ANSIBLE_COLLECTIONS_PATHS while Ansible 2.19 has
removed it. The replacement ANSIBLE_COLLECTIONS_PATH was added in
Ansible 2.10.

Debian 11 and Ubuntu 22.04 ship Ansible 2.10 while on EL we package
ansible-core 2.16 ourselves so we can rely on the replacement env var.
