[BUG] Agents can create infinite loops using functions

[Bilokin]

Hello,

there is a nice protection against infinite loops in the local python interpreter, but unfortunately, it doesn't work if an agent creates a double loop with a second loop in a function.

Code to reproduce the error
Here is an example of a correct interruption at 10000000 operations:

inter = smolagents.LocalPythonExecutor(additional_authorized_imports=[])
inter.send_tools({})
code = """
a = 0
for i in range(10_000):
    for j in range(10_000):  
        a += i+j
"""
inter(code)

And the following code proceeds till the end:

inter = smolagents.LocalPythonExecutor(additional_authorized_imports=[])
inter.send_tools({})
code = """
a = 0
def foo(a,i):
    for j in range(10_000):  
        a += i+j
    return a
for i in range(10_000):
    a = foo(a,i)
"""
inter(code)

Expected behavior
Expected InterpreterError: Reached the max number of operations of 10000000. Maybe there is an infinite loop somewhere in the code, or you're just asking too many calculations. in the second case as well.
