Declare type exports

[fubhy]

Type exports for the connect package are currently not explicitly specified.

• Adds explicit type exports for every entrypoint of the connect package.
• Puts the type exports for all packages first (in accordance with the documentation: https://www.typescriptlang.org/docs/handbook/esm-node.html)
• Removes typesVersions which shouldn't be necessary afaik (please correct me if I'm missing sth.)

Thanks for the contrib, @fubhy ❤️

We do need the "typesVersion", unfortunately.

The repo uses "Node" module resolution, and if you run make build without "typesVersion", you'll see that failing with:

src/connect-transport.ts:47:8 - error TS7016: Could not find a declaration file for module '@bufbuild/connect/protocol'. '/Users/ts/buf/connect-es/packages/connect/protocol.js' implicitly has an 'any' type.
  If the '@bufbuild/connect' package actually exposes this module, try adding a new declaration (.d.ts) file containing `declare module '@bufbuild/connect/protocol';`

47 } from "@bufbuild/connect/protocol";
          ~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Many projects are stuck with the node module resolution algorithm. It's still used when you run create-react-app. We need to support it.

Can you revert this one? Otherwise, this looks good to me!

Ah right. Good catch, thanks! Will revert tha tone in a moment.

I just ran this in a project using NodeNext module resolution - works like a charm.

LGTM!
