[PATCH docs 2/2] Minor spelling fixes

[OpenBMC Patches]

From: Milton Miller <miltonm at us.ibm.com>

Reviewing my recent update in gedit showed a few spelling typos
in code-update.md.  I also noticed the possible auto-correct
that put a backquote before an e in rest-api.md.  After that I
ran the remaining files through gedit looking for mis-spelled
words and found a few with missing letters.
