AFAICS there is no change in integrations-core for this release, but if there are in the future, shouldn't ensure the tag are named 6.xx.yy to avoid confusion?

Yes I agree, we could create a 6.53.0 tag on the same commit to prevent confusion

The backport to main 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-main main
# Navigate to the new working tree
cd .worktrees/backport-main
# Create a new branch
git switch --create backport-33255-to-main
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 1ddc8d28225bb5d2dccb7c2ccfa7b44637337c2b
# Push it to GitHub
git push --set-upstream origin backport-33255-to-main
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-main

Then, create a pull request where the base branch is main and the compare/head branch is backport-33255-to-main.
