Description

Autoware.Universe documentation is hosted in https://autowarefoundation.github.io/autoware.universe/main/ with mkdocs, but some pages outputs warnings and errors when mkdocs build is executed. We should remove these for the health of documentation.

Purpose

Remove errors/warnings from our documentation page.

Possible approaches

Run mkdocs build locally and fix the errors one by one.

Definition of done

All errors and warnings are removed from mkdocs build.

I'm currently seeing errors like the following, which comes from the scripts that converts json schema into a markdown table.
