A lot of incorrect links inside the Operator Whitepaper

I was reading through the Operator Whitepaper when I realised that there are a lot of links to pages or images that return a 404 when clicked, probably because the structure of the repos they belonged to changed. These are:

1. https://github.com/cncf/tag-security/blob/main/security-whitepaper/v2/cloud-native-security-whitepaper.md
2. https://github.com/cncf/tag-security/blob/main/security-whitepaper/v2/cloud-native-security-whitepaper.md#threat-modeling
3. https://github.com/cncf/tag-security/tree/main/supply-chain-security/supply-chain-security-paper
4. https://github.com/cncf/tag-security/blob/main/assessments/guide/self-assessment.md
5. https://github.com/cncf/tag-security/blob/main/security-whitepaper/v2/cloud-native-security-whitepaper.md#cloud-native-layers
