Minor changes to wording/punctuation on Outreach page (#407)

Mostly v minor changes to capitalization etc.
Only change of substance is wording on button that said "Support" --
given that the text above it said "The Monarch Initiative is a community
effort, and we welcome your participation!", I fully expected that
button to link to a donation page where you can support Monarch! I
suggested "Get help" instead.
