fix: remove pkg_resources for compatibility with python 3.12

pkg_resources is a package that is unavailable in python 3.12, unless
setuptools is explicitely installed. Turns out, there are replacement
functions coming from importlib_resources, which can be obtained from
the importlib-resources pypi package. This package will be installed
with tutor starting from 17.0.2.
