build: replace openbabel-wheel with openbabel

[njzjz-bot]

Problem

• openbabel-wheel has been superseded by the official openbabel package.
• Starting with Open Babel 3.2.0, users can install the Python wheels directly from openbabel on PyPI.

Change

• Replace openbabel-wheel usage with openbabel>=3.2.0.

Notes

• This keeps the same Python import path (openbabel) while depending on the upstream package name.
