fix(tests): "rejected promise … CodeWhisperer Security Scan"

Problem:
Unhandled promise rejection in "minimum" CI job:

    rejected promise not handled within 1 second: Error: command 'workbench.action.output.show.extension-output-amazonwebservices.aws-toolkit-vscode-#2-CodeWhisperer Security Scan Logs' not found

Solution:
Security Scan is not supported on the "minimum" version. Skip the test
for older vscode version.
