Replace deprecated imp module with importlib

[hugovk]

This project uses the imp module which has been deprecated since Python 3.4 and removed in 3.12:

• Raised PendingDeprecationWarning since 3.4 (2014)
• Raised DeprecationWarning since 3.5 (2015)
• Updated DeprecationWarning to say removal in 3.12 since 3.10 (2021)
• Removal planned for 3.12 (2023)

Python 3.12 is set for release on 2023-10-02 and pydevd-pycharm is one of the top 5,000 most-downloaded from PyPI.

Please could you upgrade to use importlib? The imp docs have suggestions on what to use to replace each function and constant.

Python 3.12 is now released and we are facing this issue.

I'll make this fix for the next release (meaning probably within the next 2 weeks I'll have a release with this fix out).
