[Development] Proofreaders for changes from non-native English speakers

[Mitch Curtis]

I thought it'd be useful for non-native English speakers (or even native 
English speakers) who'd like proofreading done to know who they can add as 
reviewers. There is a list of people who are willing to do language reviews 
under the Approvers and Editors section here:

I've also mentioned this under the Additional notes section here:

If you are a Gerrit user, a native or fluent English speaker and would like to 
be listed as a proofreader, please add yourself to the list.
