Which problem is this PR solving?
When connecting the gRPC exporter to a local OTLP collector (e.g., Phoenix, Jaeger) without TLS, developers encounter errors like:
The README states "By default, plaintext connection is used" (line 47), which is outdated since v0.29.0. The exporter now defaults to secure connections, but there's no clear guidance on using insecure connections for local development.
