This looks bad in UI, can we keep it single column instead?

You can view the linter failure logs here: https://github.com/frappe/frappe/actions/runs/8811181962/job/24184735736?pr=26044

If you installed the pre-commit tool, then you can run pre-commit install, once its setup, it'll automatically run every time you commit in the future.

For now you can run pre-commit run --all-files and it'll format the code as required.

Thanks @akhilnarang for all the help. I think we are good to go now.
