sphinx_tabs do not render nicely

[tdegeus]

I am using a code block in a tab environment:

.. tabs::

    .. group-tab:: C++

        .. literalinclude:: foo.txt

        Foo:

        1.  Bar::

                foo bar

with sphinx_tabs.tabs, see actual docs. The rendering is unfortunately horrible:

Yea, sphinx-tabs isn't really supported with this theme.

See https://pradyunsg.me/furo/reference/tabs/ which links to two alternative extensions that serve to replace that. I'm ambivalent on adding support for sphinx-tabs -- it's different enough that I don't feel like adopting it. OTOH, it's reasonably common.

The more pressing issue is that I can't include it in the regular manual testing that I do for this theme since it uses the same directive names as one or both of the other tabs solutions supported.
