proxy: v2.134.0 (#5802)

This release updates the proxy to use TLS version 1.3 for proxy-to-proxy
communication. Support for TLS 1.2 remains enabled for compatibility
with prior proxy versions.

This release also includes an update to the `tracing-subscriber`
dependency that may reduce latency and CPU usage.
