fix: version detection on Python 3.11

[P403n1x87]

Description of the Change

The wrong symbol name was being used on OSX, preventing the inference of the Python version from symbols.

Regressions

None expected

Verification Process

Added a new test case to check that we get the correct full version from symbols.
