- Explicitly specify correct sphinx-build binary to use.
Use versioned binary, as unversioned one may not be available
(such as when building with default python=3.10; in this case
PY_FLAVOR is py38 as this port does not yet support python 3.10,
so it pulls sphinx-build@py38 which does not install sphinx-build
as 3.8 is not default python version).
- Fix LICENSE and add LICENSE_FILE
- Do not try to install docs in build phase
