The backport to release/3.9 failed:

The process '/usr/bin/git' failed with exit code 1

stderr

``` To https://github.com/OSGeo/gdal.git ! [remote rejected] backport-10890-to-release/3.9 -> backport-10890-to-release/3.9 (refusing to allow a Personal Access Token to create or update workflow `.github/workflows/cmake_builds.yml` without `workflow` scope) error: failed to push some refs to 'https://github.com/OSGeo/gdal.git' ```

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-release/3.9 release/3.9
# Navigate to the new working tree
cd .worktrees/backport-release/3.9
# Create a new branch
git switch --create backport-10890-to-release/3.9
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 27cab6c52e5f6b04c776ed66ae791deaa169d842
# Push it to GitHub
git push --set-upstream origin backport-10890-to-release/3.9
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-release/3.9

Then, create a pull request where the base branch is release/3.9 and the compare/head branch is backport-10890-to-release/3.9.
