CONFLICT (modify/delete): .github/workflows/backport.yml deleted in HEAD and modified in 4f3ba89bee (Update Github Actions runner images).  Version 4f3ba89bee (Update Github Actions runner images) of .github/workflows/backport.yml left in tree.
Auto-merging .github/workflows/linux.yml
CONFLICT (content): Merge conflict in .github/workflows/linux.yml

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-3.12.x 3.12.x
# Navigate to the new working tree
cd .worktrees/backport-3.12.x
# Create a new branch
git switch --create backport-8660-to-3.12.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 4f3ba89bee0525b7cd5b4f30f492959dfbcf456a
# Push it to GitHub
git push --set-upstream origin backport-8660-to-3.12.x
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-3.12.x

Then, create a pull request where the base branch is 3.12.x and the compare/head branch is backport-8660-to-3.12.x.
