Add salvo to HTTP Server see_also

salvo (https://github.com/salvo-rs/salvo) is an actively maintained
hyper/tokio-based web framework (4k+ stars). Its main distinguishing
feature is simplified handler signatures that don't require complex
generic bounds, plus built-in OpenAPI generation and TLS/ACME support.
