[Bugfix] Fix VERSION FileNotFoundError bugs via pip installation

[senlyu163]

This pr fix version bugs via pip installation. It can reproduce by pip install git+https://github.com/microsoft/BitBLAS.git

After installing BitBLAS, verify the installation by running:

Python 3.10.12 (main, Jan 17 2025, 14:35:34) [GCC 11.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import bitblas
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.10/dist-packages/bitblas/__init__.py", line 156, in <module>
    from .version import __version__  # noqa: F401
  File "/usr/local/lib/python3.10/dist-packages/bitblas/version.py", line 17, in <module>
    with open(version_file_path, "r") as version_file:
FileNotFoundError: [Errno 2] No such file or directory: '/usr/local/lib/python3.10/dist-packages/VERSION'

This bug occurs because during the pip installation, the VERSION file is copied to /usr/local/lib/python3.10/dist-packages/bitblas/VERSION, while the version.py file reads from an incorrect path.

Improvement: Consolidate the version number management of BitBLAS by placing it directly into the version.py file.

�thanks @senlyu163 for your awesome contributions! I think it’s still important to maintain a VERSION text file in the root of the project to clearly indicate the version.

A better solution might be to modify version.py to detect the paths of two VERSION files. If one of them is missing, we can fall back to the other. This approach ensures flexibility while keeping the versioning clear and consistent. And that way is more aligned with the UNIX design philosophy.

Thanks for your review. I will re-commit based on your suggestions.
