Fix PathFinder.find_module AttributeError for Python 3.12

wookayin · wookayin · commit afc201a3e741 · 2023-09-21T22:50:01.000-04:00
PathFinder.find_module() has been deprecated since Python 3.4 in favor of find_spec(), and it's finally removed in Python 3.12. This line will throw an AttributeError which makes pymode completely unusable with python 3.12. It was a hacky workaround introduced in #1028. Maybe we can completely remove this workaround because it's 4 years ago and the minimum supported python version is now 3.6+.
