User validation of ScanCode and VulnerableCode docs improvements

[tsteenbe]

Conduct user testing with community members who utilize ScanCode and/or VulnerableCode to validate recent documentation changes in:

• Rewrite ScanCode docs according to Diátaxis framework #39 and
• Rewrite VulnerableCode docs according to Diátaxis framework #41

The goal is to ensure that these updates have effectively improved user experience and to identify any additional enhancements needed. This testing will help us capture feedback and implement follow-up improvements based on real user interactions.
