The request: make lacework/lw-scanner-action generate a SARIF file that we will be able to upload to GitHub Advanced Security.

Is your feature request related to a problem? Please describe

The current problem is that we cannot integrate lacework/lw-scanner-action into a workflow that engineers are used to work with. Engineers are used to access the Security tab of their GitHub repository to review findings.

Describe Preferred Solution

Make lacework/lw-scanner-action generate a SARIF file that we will be able to upload to GitHub Advanced Security.

Additional Context
