[Bug]: Pipeline targetting OU path wildcards fail

[bittrance]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

It appears the support for using OU wildcard that was merged in #538 is broken or never worked fully?

Expected Behavior

As per example in docs: https://github.com/awslabs/aws-deployment-framework/blame/325ae13fb83aad600d81494b8694362aae8f7e13/docs/user-guide.md#L377

Current Behavior

This snippet:

pipelines:
  - name: testing
    ...
    targets:
      - path:
          - /workloads/**/*
        regions: [eu-north-1]
        properties:
          template_filename: template.json

results in step function error:

{
  "errorMessage": "Path /workloads/**/* failed to return a child OU at '**'",
  "errorType": "ValueError",
  "requestId": "95da7e76-048e-480a-b38f-c0dfc4249382",
  "stackTrace": [
    "  File \"/var/task/generate_pipeline_inputs.py\", line 223, in lambda_handler\n    pipeline_input_data = generate_pipeline_inputs(\n",
    "  File \"/var/task/generate_pipeline_inputs.py\", line 151, in generate_pipeline_inputs\n    pipeline_target.fetch_accounts_for_target()\n",

    "  File \"/opt/python/organizations.py\", line 384, in get_accounts_in_path\n    ou_id = self.ou_path_to_id(path) if not ou_id else ou_id\n",
    "  File \"/opt/python/organizations.py\", line 367, in ou_path_to_id\n    raise ValueError(\n"
  ]
}
