Default Swagger support in server/v2?

[julienrbrt]

Noticed while doing #23018 that server/v2 doesn't server a swagger UI.
Is that something server/v2 should support out of the box?

The server in v1 is fairly simple: https://github.com/cosmos/cosmos-sdk/blob/d297747/server/swagger.go, hence super easily to add by chain themselves with the UI they prefer.

If we agree on not adding it, I can mention this in the v2 docs: #22531

However, we could easily create a server/v2/api/swagger if that's something we still want to support out of the box.

My two cents would say we do not need that, and that less is more in that case.

It matters how grpc-gateway will work, right now its generated from there tooling but if we remove the tooling then would it work the same way with generation?
