chore: remove env_logger from hyper example

Currently, the `hyper_echo` example uses the `tracing-log` env logger support for some weird reason. I believe this is due to Hyper previously using `log` rather than `tracing`. However, `hyper` now emits native `tracing` diagnostics, so all the `env_logger` nonsense can just be removed from the example. This branch does that.
