docs: move Sphinx object inventory for Bazel under sphinxdocs (#2117)

This moves the inventory file for Bazel objects under the sphinxdocs
directory. Inventory
files are the manifest of things that can be cross referenced from some
external source.

They're moved under sphinxdocs since these are about Bazel in general
and aren't specific
to rules_python.
