Update `Lib/test/crashers`

The Lib/test/crashers directory contains some Python files that are known to crash the interpreters. I thought it'd be useful to check in on whether they are still crashing the interpreter.

Here's what I get on a current-ish 3.14 build:

• bogus_code_obj.py: TypeError because we're missing some arguments to the CodeType constructor. I assume this would still crash if you pass the missing args though.
• gc_inspection.py: segfault
• infinite_loop_re.py: takes a long time (this is not exactly a crasher, just a ReDoS)
• mutation_inside_cyclegc.py: no error
• recursive_call.py: hangs for a long time (this sets the recursion limit to a huge value and then does runaway recursion). I believe Mark Shannon's recent interpreter changes make it so this doesn't segfault. Interestingly, I can't kill the process with Ctrl-C, maybe a bug?
• trace_at_recursion_limit.py: RecursionError (which is not a crash)
• underlying_dict.py: segfault

I'll send a PR to make bogus_code_obj.py properly segfault again. Some of the other ones should perhaps be removed.

Esamina i file elencati in Lib/test/crashers, iniziando da bogus_code_obj.py, gc_inspection.py, mutation_inside_cyclegc.py, recursive_call.py, trace_at_recursion_limit.py e underlying_dict.py. Eseguili su una build corrente di CPython e confronta il loro comportamento con il report dell’issue, verificando anche le PR collegate gh-121922 e gh-126360. Il lavoro è completato quando i crashers sono stati aggiornati o rimossi in base al loro comportamento attuale.
