docs: octeontx2: tune rst markup 

Commit 80b9414832 ("docs: octeontx2: Add Documentation for NPA health
reporters") added new documentation with improper formatting for rst, and
caused a few new warnings for make htmldocs in octeontx2.rst:169--202.

Tune markup and formatting for better presentation in the HTML view.
