The previous commit (d5cf6f6) used 'module_defaults: "{{ _proxmox_module_defaults }}"'
to template the entire defaults dict. Ansible rejects this because
module_defaults keys must be static action/module/group names at parse
time — only values may be templated.
Expose _proxmox_api_args as a flat dict of API parameters in
defaults/main.yml, and in each task file's module_defaults block use
the literal community.proxmox.proxmox and community.proxmox.proxmox_vm_info
keys with templated values pointing at the var.
