docs: Fix the docs build with Sphinx 6.0

commit 0283189e8f3d0917e2ac399688df85211f48447b upstream.

Sphinx 6.0 removed the execfile_() function, which we use as part of the
configuration process.  They *did* warn us...  Just open-code the
functionality as is done in Sphinx itself.

Tested (using SPHINX_CONF, since this code is only executed with an
alternative config file) on various Sphinx versions from 2.5 through 6.0.
