fix(ci): allow info level for test_utils in RUST_LOG

The logger capture tests need info-level logs to pass. The RUST_LOG
filter was set to error by default, which blocked the test's captured
messages. Adding test_utils=info allows those tests to work while
keeping debug logging for transport layer diagnosis.
