Intersphinx inventory

[flying-sheep]

Problem Description

I want to crosslink APIs and validate that links don’t break

Proposal

pdoc should create an intersphinx inventory, like MkDocs can do, and host it as objects.inv next to the root index.html

Alternatives

None, validating hundreds of HTML links per document build per project isn’t feasible.

Additional context

• a parser in Python: https://github.com/bskinn/sphobjinv
• sphinx extension docs: https://www.sphinx-doc.org/en/master/usage/extensions/intersphinx.html
