Dart-on-the-server page could be more compelling

[Hixie]

I searched for [dart on the server], which pointed to https://dart.dev/server.

On my laptop, this page has literally no server-specific information above the fold ("Tutorials" is below the fold).

I think this page could be rearranged to be more compelling.

• [ ] "gRPC" is a weird thing to lead with, most people don't know what that is.
• [ ] "Write HTTP servers" may not be the framing that people are looking for when they think of Dart as a server-side language. (Many web server frameworks actually build on another web server, like Apache.)
• [ ] There's no link to https://dart.dev/server/google-cloud on the page.
• [ ] DartPad is a weird thing for us to sell here since it doesn't let you use dart:io or make a server.
• [ ] There's multiple links to the Get Started doc, which also links to the "get the dark SDK" page which this page links to.

I don't know what the right solution to all this is, but it seems like we should take another pass at this page.
