Update some deps in pokemon-service-tls example (#3911)

tls-listener 0.7.0 is vulnerable to CVE-2024-28854, GHSA-2qph-qpvm-2qf7,
and RUSTSEC-2024-0341
rustls 0.20.9 is vulnerable to CVE-2024-32650, GHSA-6g7w-8wpp-frhj, and
RUSTSEC-2024-0336

We can't update them to the latest versions because we still require
hyper 0.x.
