Fix pkg resources import

The resources.files api was introduced in Python 3.9, therefore I had to use the function resources.read_text. This function has been marked deprecated since Python 3.11. As soon as the minimum requirement for prospector is Python 3.9 one could change to the resources.files api.

importlib.metadata was introduced in Python 3.8, so either the backports of those tools have to be used or this change has to be postponed until the minimum requirement is greater than Python 3.8

Python 3.9 is not yet EOL, we should probably use both with a if sys.version_info(...) guard until then.
