Once upon a time, "sphinx-build" on certain RPM platforms invoked specifically a Python 2.x version, while "sphinx-build-3" was a distro shim for the Python 3.x version. These days, none of our supported platforms utilize a 2.x version, and those that still have 'sphinx-build-3' make it a symbolic link to 'sphinx-build'. Not searching for 'sphinx-build-3' will prefer pip/venv installed versions of sphinx if they're available. This adds an extremely convenient ability to test document building ability in QEMU across multiple versions of Sphinx for the purposes of compatibility testing.
