fix(wheels): Ensure python-based builds use maj.min.patch SO versioning (#4634)

Always use patch-specific SO versioning for scikit-build-core-based
builds, even when OpenImageIO_SUPPORTED_RELEASE=ON.

Fixes #4621

Ensures that Python-based builds only bundle a single copy each of
libOpenImageIO and libOpenImageIO_Util shared libraries.

## Tests

Previously, `$ uv sync -v --reinstall
-Ccmake.define.OpenImageIO_SUPPORTED_RELEASE=1` would bundle both
.so.3.0 and .so.3.0.3 copies of libraries when installing to a local
virtual environment.

With this fix, only .so.3.0.3 copies of libraries are installed.
