documentation: conf.py: add knob for loading appropriate objects.inv

From: Quentin Schulz <quentin.schulz@theobroma-systems.com>

Yocto Project releases use a specific Bitbake release. Currently the
bitbake: mapping is pointing to the current master version of Bitbake
documentation. This is an issue if some links disappear over time and
someone is still building old documentation (which is the case on the YP
autobuilder for example). Also, the documentation at the current master
version of Bitbake might not be correct for the Yocto Project version
associated with the doc the user is currently looking at, potentially
causing confusion.

In master branch, nothing needs to be done. For release branches, the
bitbake_version variable needs to be set accordingly. See
https://wiki.yoctoproject.org/wiki/Releases for the mapping.

Excellent idea ! Thanks for the patch.

... and merged into "master-next".

I'll take care of adapting and applying it on the currently supported
release branches (dunfell, hardknott, honister). I'll do that directly
in the branches, but let me know if I should submit patches first.
Thanks again
Michael.

Done. Dunfell was actually correct, hardcoding the right Bitbake
version. Hardknott and Honister were indeed using the master version of
Bitbake objects.
Thanks again
Michael.
