Release fixup: Minor spacing and word choice fixups

Hi @wvu-r7 and @cdoughty-r7 ; although I'm out sick today, here's this week's fixups. Should be ready to build after this lands.

If any more modules get committed in the next hour or two (after 11:42am central time) please make sure there are no obvious spelling, grammar, or `msftidy.rb` errors.

Thanks!
