Description

This pull request enhances Checkov to support skipping multiple checks in a single line for Terraform configurations. Currently, individual skip comments are required for each check, which can be cumbersome. This enhancement allows specifying multiple checks to skip in a single line.

Fixes # #5381

Changes made:

Added functionality to parse multiple checks in the checkov:skip comment. Updated documentation to reflect the new capability.
