Add debug mode to TOC

This is coming from the oniro repository but the TOC is redefined in docs leaving that document dangling.

This also fixes a build warning treated as an error:

Warning, treated as error: [...]/docs/oniro/debug-mode.rst:document isn't included in any toctree make: *** [Makefile:16: build] Error
