## Summary

<!-- What's the purpose of the change? What does it do, and why? -->

Part of #18972

Both in one PR since they are in the same file.

S604
---

This PR makes [call-with-shell-equals-true
(S604)](https://docs.astral.sh/ruff/rules/call-with-shell-equals-true/#call-with-shell-equals-true-s604)'s
example error out-of-the-box

[Old example](https://play.ruff.rs/a054fb79-7653-47f7-9ab5-3d8b7540c810)
```py
import subprocess

user_input = input("Enter a command: ")
subprocess.run(user_input, shell=True)
```

[New example](https://play.ruff.rs/6fea81b4-e745-4b85-8bea-faaabea5c86d)
```py
import my_custom_subprocess

user_input = input("Enter a command: ")
my_custom_subprocess.run(user_input, shell=True)
```

The old example doesn't raise `S604` because it gets overwritten by
[subprocess-popen-with-shell-equals-true
(S602)](https://docs.astral.sh/ruff/rules/subprocess-popen-with-shell-equals-true/#subprocess-popen-with-shell-equals-true-s602)
(which is a good idea to prevent two lints saying the same thing from
being raised)

S609
---

This PR makes [unix-command-wildcard-injection
(S609)](https://docs.astral.sh/ruff/rules/unix-command-wildcard-injection/#unix-command-wildcard-injection-s609)'s
example error out-of-the-box

[Old example](https://play.ruff.rs/849860fa-0d12-4916-bdbc-64a0fa14cd9b)
```py
import subprocess

subprocess.Popen(["chmod", "777", "*.py"])
```

[New example](https://play.ruff.rs/77a54d7c-cf78-4158-bcf8-96dd698cf366)
```py
import subprocess

subprocess.Popen(["chmod", "777", "*.py"], shell=True)
```

I'm not familiar enough with `subprocess` to know why `shell=True` is
required to make `S609` raise here, but it works.
