Pin setuptools in [pipenvsetup] to avoid breaking change in 81+

[Copilot]

setuptools 81+ breaks pipenv-setup. Pin to <=80.9.0 in the [pipenvsetup] section to prevent conflicts while maintaining compatibility with versions >=60.9.3.

Changes

• Added setuptools version constraint ">=60.9.3, <=80.9.0" to [pipenvsetup] section
• Added explanatory comment for the pin

The pin is isolated to [pipenvsetup] and does not affect the [dev-packages] setuptools dependency (>=72.1.0), which is intentional per the section's design for pipenv-setup-specific dependencies.

Original prompt

Update the Pipfile in this repository by adding the following comment and setuptools pin inside the existing [pipenvsetup] section:

setuptools > 81 has a breaking change that causes pipenv-setup to fail, so we need to pin it to a version < 80.9.0

setuptools=">=60.9.3, <=80.9.0"

Ensure the new lines are placed within the [pipenvsetup] section (alongside other pipenv-setup dependencies). Do not modify other sections. Open a PR with the change.
