The backport to release_3_6 failed:

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

stderr

To https://github.com/3liz/lizmap-web-client.git
 ! [remote rejected]     backport-3815-to-release_3_6 -> backport-3815-to-release_3_6 (refusing to allow a Personal Access Token to create or update workflow `.github/workflows/tests.yml` without `workflow` scope)
error: failed to push some refs to 'https://github.com/3liz/lizmap-web-client.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_6 release_3_6
# Navigate to the new working tree
cd .worktrees/backport-release_3_6
# Create a new branch
git switch --create backport-3815-to-release_3_6
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 31ae79d1f25503b85479833ca8e1f57967ae44cf
# Push it to GitHub
git push --set-upstream origin backport-3815-to-release_3_6
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-release_3_6

Then, create a pull request where the base branch is release_3_6 and the compare/head branch is backport-3815-to-release_3_6.
