Crash due to zscore not initialised error when using the Azure generator as DAN probes are skipped

[samisouabni]

Steps to reproduce

How'd you do it?

1. Select Azure generator and run DAN probes and any other(s)
2. Setting config show_z to true
3. Skips DAN probes and crashes saying that zscore not initialised

Were you following a specific guide/tutorial or reading documentation?

No.

Expected behavior

The z score would be shown in the report, no error would be thrown by the application.

Current behavior

An error is thrown by the application and it stops.

garak version

0.10.1

Additional Information

1. Mac OSx and Windows
2. 3.12.8
3. direct repository checkout with git
4. The error is at garak/evaluators/base.py, line 174 should be duplicated into the else statement, after line 182.
5. Config provided below:

  verbose: 0
  parallel_requests: false
  parallel_attempts: false
  show_z: true

6. Any relevant hardware or resource information
