[jsweep] Clean autofix_code_scanning_alert.cjs

[github-actions]

Summary

Cleaned autofix_code_scanning_alert.cjs to use modern JavaScript patterns and reduce verbosity.

Context

This file runs in github-script context and handles creating autofixes for code scanning alerts via the GitHub REST API.

Changes Made

Code Improvements

1. Eliminated unnecessary variable - Removed autofixItem intermediate variable, used message directly throughout for consistency
2. Condensed return objects - Converted multiline return objects to single-line format (e.g., return { success: false, error: "..." })
3. Used spread operator - Replaced explicit owner: context.repo.owner, repo: context.repo.repo with ...context.repo
4. Removed unused variable - Removed result variable from github.request call since it wasn't being used
5. Simplified headers - Converted multiline headers object to single-line format for consistency
