Add vulcan-repository-sctrl check

[danfaizer]

This PR adds the vulcan-repository-sctrl check, which provides insights into whether a Git repository has security controls in place.

The check primarily reports two possible findings:

• Informational finding: Security controls detected in the repository.
• Medium severity finding: Repository missing security controls.

If security controls are detected in the repository, the check provides a list of these controls in the "check finding resources" table.

Below is an example of how the check's output appears in Lava:

With security controls in place:

IMPACT
A repository lacking security controls can lead to expose sensitive information, enable unauthorized access, and other security risks.

RECOMMENDATIONS
- Add a security scanner to your CI/CD pipeline to detect security issues in your codebase.
- If you don't have any default scanner, consider using Lava action in your CI/CD pipeline.
