Before this patch, building htmldocs on opensuseLEAP works
fine:
# make htmldocs
Available Python versions:
/usr/bin/python3.11
Python 3.6.15 not supported. Changing to /usr/bin/python3.11
Python 3.6.15 not supported. Changing to /usr/bin/python3.11
Using alabaster theme
Using Python kernel-doc
...
As the logic detects that Python 3.6 is too old and recommends
intalling python311-Sphinx. If installed, documentation builds
work like a charm.
Yet, some develpers complained that running python3.11 instead
of python3 should not happen. So, let's break the build to make
them happier:
$ make htmldocs
Python 3.6.15 not supported. Bailing out
You could run, instead:
/usr/bin/python3.11 tools/docs/sphinx-build-wrapper htmldocs \
--sphinxdirs=. --conf=conf.py --builddir=Documentation/output --theme= --css= \
--paper=
Python 3.6.15 not supported. Bailing out
make[2]: *** [Documentation/Makefile:76: htmldocs] Error 1
make[1]: *** [Makefile:1806: htmldocs] Error 2
make: *** [Makefile:248: __sub-make] Error 2
It should be noticed that:
1. after this change, sphinx-pre-install needs to be called
by hand:
$ /usr/bin/python3.11 tools/docs/sphinx-pre-install
Detected OS: openSUSE Leap 15.6.
Sphinx version: 7.2.6
All optional dependencies are met.
Needed package dependencies are met.
2. sphinx-build-wrapper will auto-detect python3.11 and
suggest a way to build the docs using the parameters passed
via make variables. In this specific example:
/usr/bin/python3.11 tools/docs/sphinx-build-wrapper htmldocs --sphinxdirs=. --conf=conf.py --theme= --css= --paper=
3. As this needs to be executed outside docs Makefile, it won't run
the validation check scripts nor build Rust documentation if
enabled, as the extra scripts are part of the docs Makefile.

The sphinx-pre-install code has some logic to deal with Python
version, which ensures that a minimal version will be enforced
for documentation build logic.
Move it to a separate library to allow re-using its code.
No functional changes.
