Checks

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of pixi, using pixi --version.

Reproducible example

pixi run python sig.py
kill -INT <pixi run PID>
kill -INT <python PID>

Issue description

When you send a signal to the pixi parent process it's not forwarded to the child.

import signal
import time

def signal_handler(signum, frame):
    print(f"Signal handler called with signal {signum}")

signal.signal(signal.SIGINT, signal_handler)

while True:
    time.sleep(1)

Expected behavior

Should forward signals
