Clarify references to case studies in readme

Nobody has claimed this yet.

> In the above sample output, we run capa against an unknown binary (suspicious.exe), and the tool reports that the program can send HTTP requests,

Instead of this you can mention properly with due respect that you have used open source project which is based on malware analysis kind of tool and what all things it runs and showcase how capa can detect all those as example . In this way people will not have wrong image about al-khaser project which is important because it also deserves equal respect as open source project which is unique and well maintained instead of been shown as "unknown suspicious binary" plus they can read al-khaser code (https://github.com/LordNoteworthy/al-khaser) and understand all how it works and what all things it do plus how project capa can detect all those things successfully from exe file so all together this would give best open picture to all users.

Locate the sample-output passage in the README and review the linked al-khaser project for accurate context. Update the reference so it credits al-khaser as an open-source malware-analysis project rather than calling the binary unknown and suspicious, while explaining the capa example clearly. Done means the wording is respectful and technically accurate.
