[Internal]: Reformat CSPM/KSPM guides

[benironside]

Description

While reviewing a PR that touched the solutions/security/cloud/cspm and kspm (cloud security posture management and kubernetes posture security management) integrations docs, Florent suggested some format improvements. They are better made in a follow-up PR to minimize merge conflicts with another soon-to-be-merged PR that affects the same pages.
