Publish PokemonService generated server crate to crates.io

[hlbarber]

Publishing the crate would trigger a docs.rs build. This would allow the aws-smithy-http-server documentation, and documentation in general, to reference generated items.

What generated items would we reference from aws-smithy-http-server?

[hlbarber]

In some cases types from aws-smithy-http-server are used in the context of a generated API.

For example:

• MakeServiceWithConnectInfo is a product of the make_service_with_connect_info on the generated service.
• Operations are passed to the operation setters.
• Plugins are passed to build_with_plugins.

[david-perez]

To avoid aws-smithy-http-server taking a dev dependency on a generated SDK like the Pokémon service's (which is sizable and could slow down compilation), an alternative is to have the book depend on the generated SDK and have aws-smithy-http-server + the user's generated SDK link to the book.

I think this can be deprioritized now that we have #2027 which allows us to write examples involving the examples workspace.
