refactor: Simplify quinn rpc test (#39)

* Delete the setup of a local quinn connection for tests

replace with the new tools in quic-rpc v0.17.3

* use doc_auto_cfg

also fix warning regarding urkls in readme

to test:

RUSTDOCFLAGS="--cfg iroh_docsrs" cargo +nightly doc --all-features --no-deps --open
