[docs] Fix Git Invocation for Google Cloud

The Google Cloud docs builder does not manage to get file versions
because it has to cross a filesystem boundary when attempting to find
the git directory for the repository.

This change ensures that git starts in the right working directory,
regardless of where doxygen is invoked from.
