(backport of #10089 to 3.2 branch)
We have received many reports that Fluent Bit cannot send data to the OpenTelemetry Collector over a plain text communication, this is happening because we enabled http2 by default so when the Otel Collector receives the request (PRI * HTTP/2.0...) it drops the connection.
This PR switches http2 default to off so users don't run into this problem.
