modify the default 'settings.yml' text for solving api_key get Nonetype error

Issue resolved for TypeError: 'NoneType' object is not subscriptable concerning missing path for read/write of settings.yml file.

if firstly clone this project and executed without settings.yml, the default flow was created the new settings.yml file with TEXT variable include virustotal api key, but the yml format is NOT correct, so i just modify the TEXT variable content.

Thank you. I recently edited the TEXT output format and it now reads/writes correctly. My Python black formatter was overwriting the original format. I'll apply a comment (locally) to exclude from formatting.
