Fix UNKNOWN package name when installing with --no-build-isolation

[AshadowZ]

Problem Description

When installing this package using pip install . --no-build-isolation (which is common practice for CUDA extensions to reuse the host's PyTorch environment), pip skips creating a temporary build environment and instead relies on the host system's setuptools.

If the host's setuptools version is older than 61.0.0, it does not support PEP 621 and ignores the [project] metadata table in pyproject.toml. As a result, setup.py fails to retrieve the package name and version, causing the package to be built and installed as:
UNKNOWN-0.0.0

Proposed Changes

This PR modifies setup.py to explicitly pass the name and version arguments to the setup() function.
