Fix Pythia8 CI testing

jackal1-66 · sawenzel · commit 28f0599860c3 · 2025-12-20T16:42:16.000+01:00
The Pythia8() function exists already in the Pythia namespace loaded with ROOT, so when executing the macro a function redefinition error was thrown. By replacing the name to pythia8() the problem is solved.
