[bugfix] Fix lint-and-format workflow detached HEAD issue

[snomiao]

Fixes this problem:

• refactor: Improve litegraph preprocessing for i18n collection · Comfy-Org/ComfyUI_frontend@3700457

it works now:

Summary

• Fixed the lint-and-format GitHub Action workflow failing with "fatal: You are not currently on a branch" error
• Changed checkout ref from head.sha to head.ref to properly checkout the PR branch instead of creating a detached HEAD state

Problem

The workflow was failing in the "Commit changes" step when trying to push auto-fixes because:

1. Using ref: ${{ github.event.pull_request.head.sha }} checks out a specific commit SHA
2. This creates a detached HEAD state (not on any branch)
3. When the workflow tries to git push, it fails because there's no branch to push to

Solution

Changed to ref: ${{ github.event.pull_request.head.ref }} which:

• Checks out the actual PR branch name
• Allows the workflow to push commits back to the PR branch
• Maintains the same security (only works for PRs from the same repo, not forks)

Test Plan

• Workflow runs successfully on PRs from the same repository
• Auto-fixes are committed and pushed back to the PR branch
• Fork PRs still show the manual fix message (unchanged behavior)

Fixes the CI/CD failure seen in #5297
