fix(setup): pin setuptools version to resolve pkg_resources ModuleNotFoundError

[anilkir]

Solved Problem

Support for pkg_resources was removed in setuptools v82.0.0, which causes a ModuleNotFoundError when compiling uavcan drivers via pydronecan. pydronecan imports pkg_resources here.

Setuptools changelog: https://setuptools.pypa.io/en/stable/history.html#deprecations-and-removals

Solution

Pinned setuptools upper version in the requirements.txt.

Changelog Entry

For release notes:

Fix: pin setuptools<82.0.0 to restore pkg_resources availability for uavcan/dronecan build

Sorry you had to find this in a laptop revival resetup scenario and thanks for contributing the fix 🙏

I'm pretty sure for Ubuntu 26.04 we'll anyways have to update some things but at least we can still work with available versions this way.
