openapi-python-client doesn't find autoflake even when on $PATH

Describe the bug
Even when autoflake is on the PATH, openapi-python-client seems to claim it isn't.

To Reproduce
Steps to reproduce the behavior:

⊙  python3.10 -m venv venv && venv/bin/python -m pip install --quiet openapi-python-client

⊙  ls venv/bin/
Activate.ps1  activate.csh   autoflake  blackd  isort                   openapi-python-client  pip3     pyflakes  python3
activate      activate.fish  black      httpx   isort-identify-imports  pip                    pip3.10  python    python3.10

⊙  PATH=venv/bin:$PATH

⊙  type -a openapi-python-client
openapi-python-client is venv/bin/openapi-python-client

⊙  type -a autoflake
autoflake is venv/bin/autoflake

⊙  autoflake --help
<help output>

⊙  openapi-python-client generate --path openapi.yaml
Generating foo-client
Error(s) encountered while generating, client was not created

autoflake failed

/bin/sh: autoflake: command not found

Expected behavior
autoflake is found

Additional context
I haven't investigated carefully yet, though I'm possibly happy to do so after getting my client working, but I suspect the issue is here:

https://github.com/openapi-generators/openapi-python-client/blob/9cea5af550a629415874fb4007e57774af9a5382/openapi_python_client/__init__.py#L157

where commands are executed in a subshell.

As I say I definitely don't fully understand the internals of the project, but generally I think using shell=True is worth trying to avoid as often as possible. I suspect here from what I see, someone can specify arbitrary commands to run post-generation and is doing so as a str in the config? If it's not appealing to change that instead to be a list (and then you don't need shell=True), you could also use shlex.split, which is equally a bit fiddly but would mean you don't spawn a subshell. Or alternatively you could assume the things are installed to the same Python interpreter as openapi-python-generator, and invoke python -m black or python -m autoflake by using sys.executable on the same Python openapi-python-generator is run with, without needing to search $PATH.

Comece em openapi_python_client/init.py por volta da linha 157 e reproduza o relatório com um ambiente virtual, autoflake no PATH e o openapi.yaml fornecido. Rastreie como o comando de geração invoca o autoflake e verifique se a geração é bem-sucedida quando o executável está disponível no PATH.
