Remove iac-sast job from SAST-IaC templates

Proposal

As mentioned here, the following templates contain an iac-sast job:

The point of this issue is to remove this iac-sast job, because:

  • it's an anti-pattern that shouldn't be repeated

This is a breaking change, since it's possible that customers have overridden this job for some reason, however, since the usage of this iac-sast job is undocumented, perhaps this is acceptable.

Implementation Plan

Move the contents of the iac-sast job to the kics-iac-sast job in the following templates:

Make sure not to copy the rules block, since it's unnecessary.
