Document air-gapped (offline) IaC scanning installation for on-prem instances

Problem to solve

Add a new IaC scanning offline directions section to the Specific scanner instructions section similar to the SAST offline directions.

Further details

Currently, we have a list of other scanners documented. A recent interaction with a customer revealed that their GitLab Admin team didn't know how to install/operate the IaC functionality offline. On further inspection, we realized that the document didn't have the necessary details in the larger list. Those instructions also don't seem to be in the general Infrastructure as Code scanning section.

Proposal

• Add documentation on how to install and operate IaC in an offline (air-gapped) environment
• Add link in the Specific scanner instructions to point to the documentation
