Information about bug

During bench udpate there is this warning

Installing helpdesk
$ /workspace/development/frappe-bench/env/bin/python -m pip install --quiet --upgrade -e /workspace/development/frappe-bench/apps/helpdesk 
  DEPRECATION: Legacy editable install of helpdesk==0.10.0 from file:///workspace/development/frappe-bench/apps/helpdesk (setup.py develop) is deprecated. pip 25.0 will enforce this behaviour change. A possible replacement is to add a pyproject.toml or enable --use-pep517, and use setuptools >= 64. If the resulting installation is not behaving as expected, try using --config-settings editable_mode=compat. Please consult the setuptools documentation for more information. Discussion can be found at https://github.com/pypa/pip/issues/11457

possible fix is to migrate to pyproject.toml new standard
