Browserker in DAST should not add auth details if auth_url is empty
Problem to solve
When removing webdriver auth for browserker, the conditional for only executing auth provided an auth_url existed was not added to the configuration generation section of browserker_configuration_file.py
Proposal
Only add auth details if auth_url is not None.
Intended users
What does success look like, and how can we measure that?
The [AuthDetails] section for browserker configs is empty if auth_url is None.
