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/3.7 release/3.7
# Navigate to the new working tree
cd .worktrees/backport-release/3.7
# Create a new branch
git switch --create backport-8516-to-release/3.7
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 78efa59719ae3567a0bbc02e62d37ff5d858894f,4d3c1d4d2450ab01e6534ee59b99e0175ee290ed,f9846d52ff9b983d4f2ae6eab9aa9eabdb8726f3,6dfc9630652a9b58820bca29be47bfe603403524,b827f22bae8f1b48cba2cf3bf18099dceabb9229,4d6bb03a913e8fa158972fe3130ffa8d3141291d,b4755d9444b8ad738c1e7366eaf550d6b249d70c
# Push it to GitHub
git push --set-upstream origin backport-8516-to-release/3.7
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-release/3.7

Then, create a pull request where the base branch is release/3.7 and the compare/head branch is backport-8516-to-release/3.7.
