Grpc DevUI output form resizing and missing test icons

[kshpak]

Describe the bug

[User Interface related]

1. Output form height increasing at every method call
   Causes: https://github.com/quarkusio/quarkus/blob/main/extensions/grpc/deployment/src/main/resources/dev-templates/service.html#L102

2. Tool(test) icon for redirecting to service methods is missing for Health endpoint and Steaming services (can be accessed only by directly accessing service URL e.x. http://localhost:8080/q/dev/io.quarkus.quarkus-grpc/service?name=helloworld.Streaming)

Expected behavior

1. Output form height is properly adjusted by the output size
2. Test redirect icons are present for Health and Streaming services

Actual behavior

No response

There's one more thing that's wrong, the name of the streaming bean is the name of the generated class instead of the user's class. I will try to fix it too.

[michalszynkiewicz]

all the things but the service name are fixed, I'll leave the issue open to handle the service name as a part of it, if you don't mind
