chore(deps): Pin setuptools~=81.0

pkg_resources has been removed from Setuptools v82.0.0

Razorpay 1.2.0 depends on pkg_resources. razorpay/razorpay-python#307

Packages from dev-requirements (e.g. moto) ask for setuptools>=x, that fetches the latest setuptools, ignoring the previous constraints.
So, pin setuptools in dev-requirements.txt
