Pact Foundation

*FYI*
by trial and error I checked that the example project
<https://github.com/pact-foundation/pact-plugins/tree/main/examples/gRPC/area_calculator/consumer-jvm>

works only up until `pact-protobuf-plugin`  version *0.1.8*
*0.1.9 and 0.1.10* are failing to run

Oh, we now default the plugin to IP4 addresses to be able to run from within docker containers. In the manifest file, there is a `"hostToBindTo"` field. Try change that from `"127.0.0.1"` to `"::1"`

there is a change in behaviour for sure, now it fails with
```08:03:26.959 [Test worker] ERROR a.c.d.pact.consumer.dsl.PactBuilder - Plugin process did not output the correct startup message in 10000 ms - got null```

with `127.0.0.1`
it fails with
```Caused by: io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: /0:0:0:0:0:0:0:1:58408 ```
I saw it in some other thread here as well

Ok, maybe just remove that field. I'm rolling out a fix to Pact-JVM now as well
