The backport to release-2.9.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 branch
git switch --create backport-13213-to-release-2.9.x origin/release-2.9.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x 5df56a4e0da96d41b192c7289a24d452b221d76d

When the conflicts are resolved, stage and commit the changes:

git add . && git cherry-pick --continue

If you have the GitHub CLI installed:

# Push the branch to GitHub:
git push --set-upstream origin backport-13213-to-release-2.9.x
# Create the PR body template
PR_BODY=$(gh pr view 13213 --json body --template 'Backport 5df56a4e0da96d41b192c7289a24d452b221d76d from #13213{{ "\n\n---\n\n" }}{{ index . "body" }}')
# Create the PR on GitHub
echo "${PR_BODY}" | gh pr create --title 'chore: [release-2.9.x] docs: fix query example for labels and values' --body-file - --label 'size/XS' --label 'type/docs' --label 'backport' --base release-2.9.x --milestone release-2.9.x --web

Or, if you don't have the GitHub CLI installed (we recommend you install it!):

# Push the branch to GitHub:
git push --set-upstream origin backport-13213-to-release-2.9.x

# Create a pull request where the `base` branch is `release-2.9.x` and the `compare`/`head` branch is `backport-13213-to-release-2.9.x`.

# Remove the local backport branch
git switch main
git branch -D backport-13213-to-release-2.9.x

It doesn't look like this was documented in 2.9 or 3.0, so probably a new feature. Leaving this fixed in main and not backporting this PR.
