Ember Initiative Page updates

[marcoow]

We're about to actually start the Ember initiative and need to make some changes to the page:

• Change "The Embroider initiative was supported by a large group of individuals and companies that build on Ember" to "The Ember and Embroider initiatives are supported by a large group of individuals and companies that build on Ember"
• make a new versions of the sponsor logos graphic (see
  https://github.com/mainmatter/mainmatter.com/blob/master/static/assets/images/ember-initiative/sponsor-logos.jpg) and add it to the Ember initiative page above "Why sponsor?"
• Replace "As we have proven with the Embroider initiative, we're able to deliver tangible results that push the ecosystem forwards." with "Initiative sponsors get a say in deciding on the team's priorities and quarterly roadmaps to ensure they get the most out of their investment."

make a new versions of the sponsor logos graphic (see
https://github.com/mainmatter/mainmatter.com/blob/master/static/assets/images/ember-initiative/sponsor-logos.jpg) and add it to the Ember initiative page above "Why sponsor?"

Do you mean: a) update the design of the visual to be in line with our current style or b) change which sponsor logos are shown?
