Add support for Python 3.13

[tdruez]

The main issue here:

AssertionError: 0 != 1 : Invalid python version: 313. Must be one of: 27, 36, 37, 38, 39, 310, 311, 312, 2.7, 3.6, 3.7, 3.8, 3.9, 3.10, 3.11, 3.12

This is problematic as this issue will resurface each time a new Python version is released.

• Short-term fix: add Python 3.13 to this list.
• Long term: refactor that code to support future Python releases without a hardcoded list.

@tdruez thanks, checking this one

Release https://github.com/aboutcode-org/python-inspector/releases/tag/v0.13.1 says to fix this, so can we close this?

@sschuberth yes!
