[pylint-backport]

The backport to maintenance/4.0.x failed:

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

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-maintenance/4.0.x maintenance/4.0.x
# Navigate to the new working tree
cd .worktrees/backport-maintenance/4.0.x
# Create a new branch
git switch --create backport-10732-to-maintenance/4.0.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 7f7f7b85f96f881daf18f1a21418bda831af2ca5
# Push it to GitHub
git push --set-upstream origin backport-10732-to-maintenance/4.0.x
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-maintenance/4.0.x

Then, create a pull request where the base branch is maintenance/4.0.x and the compare/head branch is backport-10732-to-maintenance/4.0.x.

Nice catch ! Not sure if the backport manual cherry-pick is necessary. Are we even checking the primer on the maintenance branch ?

[jacobtylerwalls]

Good point, probably not.
