Fix Script Injection Vulnerability in RL Scanner

Summary

This PR fixes a potential script injection vulnerability by avoiding direct shell interpolation of user inputs. Instead, user-provided values are safely passed through environment variables.

Changes

• Added ARTIFACT_PATH and VERSION to the env: block
• Updated the shell script to use $ARTIFACT_PATH and $VERSION instead of ${{ inputs.* }}
