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.
