STEPS TO REPRODUCE

Run example playbook:

- hosts: localhost
  gather_facts: false
  tasks:
    - name: Create Temporary File
      ansible.builtin.tempfile:
        state: file
      register: temp_file_result
    - name: Convert certificate
      community.crypto.x509_certificate_convert:
        src_path: "{{ temp_file_result.path }}"
        dest_path: "{{ temp_file_result.path }}.pem"
        format: pem
      register: cert_convert_result
    - debug:
        var: cert_convert_result

EXPECTED RESULTS

Playbook should fail on task "Convert certificate" because the input (src_path) is not a valid certificate.

ACTUAL RESULTS

Playbook completes successfully, with the task "Convert certificate" showing as changed.
