Resolution impossible error raised when packages resolvable

针对 Python 3.9、3.11 和 3.13 重现列出的 python-inspector 命令，然后通过 python_inspector/resolve_cli.py、api.py 和 resolution.py 跟踪失败，尤其是 get_requirements_from_python_manifest。完成标准是：能够为 Python 3.9 和 3.10 解析出兼容版本，而 Python 3.13 的不兼容性会产生描述性的解析错误，而不是所示的 AttributeError。

Running ORT on a python project with python-inspector gives the following error when using non-production tags:

The dependencies are as follows:

greenlet==3.0.0rc3
gevent==23.9.1

The two dependencies are resolvable by PIP, tested with Python 3.9.3 and 3.11.7 with python>=3.13 it is not resolvable anymore:

.venv/bin/pip install gevent==23.9.1 greenlet==3.0.0rc3
...
Successfully installed gevent-23.9.1 greenlet-3.0.0rc3 setuptools-80.9.0 zope.event-5.1.1 zope.interface-7.2

Running python inspector on this file gives the following outputs:

What I am expecting is that for 3.13, the error could be more descriptive to indicate it is unresolvable due to incompatibility of the package versions with python 3.13. For 3.10 and 3.9 it should work because the packages are compatible and resolvable, not sure why with 3.11 it does work in the end.

Important to note: none of this happens with greenlet==3.0.0 aside from error with 3.13, which is expected.
