Ansible failure: Invalid variable name in 'register' specified: 'import'

[mloskot]

While building Windows 2019 image (for sig-windows-dev-tools), I've noticed the following Ansible error:

...
    virtualbox-iso: TASK [load_additional_components : Load additional Docker images] **************
    virtualbox-iso: ERROR! Invalid variable name in 'register' specified: 'import'
    virtualbox-iso: skipping: [default] => (item=)
    virtualbox-iso: skipping: [default]
2023/05/03 20:21:14 [INFO] (telemetry) ending ansible
==> virtualbox-iso: Error executing Ansible: Non-zero exit status: exit status 1
==> virtualbox-iso: Step "StepProvision" failed
==> virtualbox-iso: [c] Clean up and exit, [a] abort without cleanup, or [r] retry step (build may fail even if retry succeeds)?

I have near-zero experience with Ansible and searching the web for this error does not return any useful results.

I started wondering if the import used here is a reserved keyword in Python-powered Ansible:

image-builder/images/capi/ansible/windows/roles/load_additional_components/tasks/url.yml

Lines 75 to 76 in 3711064

	register: import
	until: import is not failed

I guess it would have been caught already, unless it's been changed in in the latest Ansible. The word import is not listed as special keyword - https://docs.ansible.com/ansible/latest/reference_appendices/playbooks_keywords.html

Any ideas what is the error about?
