OK, the problem is with lookup plugin.
It is executed on ansible control host with permissions of user that run ansible-playbook and become: yes don't elevate plugins' permissions.

To overcome this, capture result of user task and use its output in further tasks:

- user:
    name: "{{ item }}"
    shell: /bin/bash
    group: docker
    generate_ssh_key: yes
    ssh_key_comment: "ansible-generated for {{ item }}"
  with_items:
    - ansible5
    - ansible6
  register: new_users
  become: yes

- debug: msg="user {{ item.item }} pubkey {{ item.ssh_public_key }}"
  with_items: "{{ new_users.results }}"

Although you need to delegate some of this tasks, the idea will be the same.
