Calling the generator from cli works with different syntax from documentation

Describe the bug

Calling from cli using the suggested method with python -m does not work.

python -m openapi-python-client --version
PATH_TO_PYTHON\python.exe: No module named openapi-python-client

Using underscores, however, does work (python -m openapi_python_client -version):

python -m openapi_python_client --version
openapi-python-client version: 0.24.3

OpenAPI Spec File

Not applicable

Desktop (please complete the following information):

• OS: Windows 11 (Microsoft Windows NT 10.0.26100.0)
• Python Version: [e.g. 3.12.7]
• openapi-python-client version [e.g. 0.24.3]

Additional context

Running from a powershell instance in VSCode with a conda environment selected as a Python interpreter.

Would it be possible to add a line to the documentation mentioning the call with python -m?

从 issue 中链接的 README 位置开始，将其中记录的 python -m 调用方式与报告中所示的可正常工作的下划线形式进行比较。在项目的 CLI 上下文中验证该命令，然后更新文档，使受支持的调用方式明确且一致。完成的标准是新手可以成功按照 README 中的命令操作。
