Thanks! It's just lint errors:

cheatsheets/Kubernetes_Security_Cheat_Sheet.md:400 MD036/no-emphasis-as-heading/no-emphasis-as-header Emphasis used instead of a heading [Context: "Utilize Pod Security Standards..."]
cheatsheets/Kubernetes_Security_Cheat_Sheet.md:410:283 MD009/no-trailing-spaces Trailing spaces [Expected: 0 or 2; Actual: 1]
