Error in Parsing the YAML Config File

Issue Summary:

I am encountering a warning when attempting to run a scan with the -tdc flag while passing a YAML file containing the configuration data.

Details:
Warning Message:
[11:36:22] WARNING actor1 is required config_data_handler.py:34

Steps to Reproduce:

1. Copy-paste the example configuration from the README file into a YAML file.
2. Run the following command:

offat -f openapi.json --server http://[serveraddress] -tdc test_data_config.yaml -o output.yaml -of yaml

Environment:

Tested on both Ubuntu and Windows.
Installed the tool using pip.
Also tested manual installation and running with poetry.

Despite following the example provided in the README, I continue to receive the warning about actor1 being required. I have verified the YAML file's structure and content, but the issue persists across different environments and installation methods. The content of the YAML file is:

actors:
  - actor1:
    request_headers:
      - name: Authorization
        value: Bearer [Token1]
      - name: User-Agent
        value: offat-actor1

    query:
      - name: id
        value: 145
        type: int
      - name: country
        value: uk
        type: str
      - name: city
        value: london
        type: str

    body:
      - name: name
        value: actorone
        type: str
      - name: email
        value: actorone@example.com
        type: str
      - name: phone
        value: +11233211230
        type: str

    unauthorized_endpoints: # For broken access control
      - "/store/order/.*"

Compare the README configuration example with the YAML shown in the issue, then inspect config_data_handler.py:34 and the -tdc command path. Reproduce the warning with the provided offat command and verify that the configuration is accepted without the actor1 warning while its fields remain available to the scan.
