error if you set grpc.server.port to -1

[sdelamo]

Docs:

The server by default runs on port 50051, however you can configure which port the server runs on by setting grpc.server.port to whichever value you wish (a value of -1 will use a random port).

Steps to reproduce

% mn --version
Micronaut Version: 2.0.0.M3
JVM Version: 11.0.6
% mn create-grpc-app foo
| Application created at /Users/sdelamo/Downloads/demo-12/foo
% cd foo 
foo % vi src/main/resources/application.yml 
foo % cat src/main/resources/application.yml 
micronaut:
  application:
    name: foo
grpc:
  server:
    port: -1
% ./gradlew run

> Task :compileJava
Note: /Users/sdelamo/Downloads/demo-12/foo/build/generated/source/proto/main/java/foo/Foo.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
