CMP-3618 broke kubernetes remediation into two

[vickeybrown]

Description:

• Split the Kubernetes remediation for chronyd_configure_local_socket
  between OCP 4.12 (RHEL 8) and OCP 4.13+ (RHEL 9)

Rationale:

• OCP 4.12 is based on RHEL 8, which does not support all the systemd
  hardening directives used in the RHEL 9 version

• OCP 4.13+ is based on RHEL 9, which fully supports these hardening
  directives

• Fixes # CMP-3618

Review Hints:

• The generated file should contain both MachineConfigs with the correct
  version annotations and different service file content (decode the URL-encoded
  data to verify)
• Key difference: Line 11 has '<4.13.0' with shorter service file; Line 28
  has '>=4.13.0' with full hardening

Hi @vickeybrown. Thanks for your PR.

I'm waiting for a ComplianceAsCode member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
