[codespell] start fixing all the typos

this is the inital patch of applying codespell to nova.
codespell is a programing focused spellchecker that
looks for common typos and corrects them.

i am breaking this into multiple commits to make it simpler
to read and will automate the execution of codespell
at the end of the series.
