new logic in sdk/_version not working if included in another project

[marcelkb]

hi,

since the new update code was added in sdk/_version to support the new versioning:

def _get_version() -> str:
    current_file = Path(__file__)
    pyproject_path = current_file.parent.parent / "pyproject.toml"

    try:
        with open(pyproject_path, "rb") as f:
            pyproject_data = tomllib.load(f)
        return str(pyproject_data["project"]["version"])
    except (FileNotFoundError, KeyError, Exception):
        raise ValueError("Failed to read version from pyproject.toml")

SDK_VERSION = _get_version()

this code is not working if the lib is exported and included in another project.
the pyproject.toml dont get exported by default.
another problem is that the calculated relative path points to
/venv/Lib/site-packages/pyproject.toml
