Text: Bringing the brightest nonprofit newsrooms together for intensive business training, June 16 and 17

Button: "Learn More" that links to: https://inn.org/inn-days-2020/

No other homepage edits. Do the thing on staging, we'll have them review, and then move it live.

The above questions are obsoleted by the questions in INN/inn#121, and should be answered in that issue, please.

Edits requested:

• Hero image - crop photo tighter to show less black space at the top and on the left/right sides
• Description text - Fran wants to center the title, text and "Learn more" button. Change the description text under INN Days 2020 to say "June 16 and 17, The Westin Hotel Old Town, Alexandria, Virginia"

Let me know if the centering isn't possible.

Script I used to quickly generate the images:

#! /usr/bin/env bash
for WIDTH in 400 800 1200 2000
do
	convert RN-Elizabeth-Glenn-uses-thermometer-at-IHS.jpg -resize ${WIDTH}x${WIDTH} RN-Elizabeth-Glenn-uses-thermometer-at-IHS-${WIDTH}.jpg
done

But preferentially we'd make it so this can be managed using the WordPress admin rather than tracking these images in git.
