Content: update pricing page

[agjohnson]

I have some structure changes and content changes here, but won't focus too much on this page. I have a branch already, but just tracking this on our roadmap.

Additionally:

• [x] Update pricing style and tune page information
• [x] Add feature detail list
• [x] Add enterprise call out to pricing page

Next steps: Link PR, and if it doesn't move this sprint, backlog it.

Actually, if I can't finish this up on my thurs/fri this week, lets try to merge what I have completed. I left this about 95% done, so shouldn't take much work.

Yea, as long as it's better than what we have, I'm 👍 on merging and iterating.

Do we have a PR for this?

[ericholscher]

I think @agjohnson has the code locally, but I'd love to get it shipped since this page is already getting traffic:
