We know the name of the folder in which the VM has been running. If we didn't, or if it changed for any reason, we could use the vmware_guest_find module to dynamically discover the location:

- name: Find vm folder location
  vmware_guest_find:
    hostname: "{{ vsphere_host }}"
    username: "{{ vsphere_username }}"
    password: "{{ vsphere_password }}"
    validate_certs: "no"
    name: "yet_another_example_vm"
  register: vm_folder

The name of the folder will be registered as vm_folder.
