DOCS: User validation of docs improvements

[tsteenbe]

Conduct user testing with community members who utilize below listed projects to validate recent documentation changes made in:

• CRAVEX-Docs: Improve and reorg the ScanCode.io docs #43
• CRAVEX-Docs: Improve and reorg the DejaCode docs #42
• DOCS: Rewrite AboutCode toolkit docs according to Diátaxis framework #46
• CRAVEX-Docs: Improve and reorg PurlDB docs #50

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.
