[dependabot[bot]]

Bumps google.golang.org/grpc from 1.66.2 to 1.67.0.

Release notes

Sourced from google.golang.org/grpc's releases.

Release 1.67.0

Bug Fixes

• ringhash: when used with multiple EDS priorities, fix bug that could prevent a higher priority from recovering from transient failure. (#7364)
  • Special Thanks: @​atollena

Behavior Changes

• In accordance with RFC 7540, clients and servers will now reject TLS connections that don't support ALPN. This can be disabled by setting the environment variable GRPC_ENFORCE_ALPN_ENABLED to false (case insensitive). Please file a bug if you encounter any issues with this behavior. The environment variable to revert this behavior will be removed in an upcoming release. (#7535)
