grpc.server.health-service.type=ACTUATOR doesn't exist in the lastest version

[mrttrifork]

According to https://grpc-ecosystem.github.io/grpc-spring/en/actuator.html

grpc:
  server:
    health-service:
      type: ACTUATOR

Should be a property, but in the current version grpc-client-spring-boot-starter-3.1.0.RELEASE it doesn't exist within the code base.

I can see that it exists on master, and will be part of the next release.

Maybe hide it until grpc-client-spring-boot-starter-3.2.0.RELEASE is released, or write from version 3.2.0.RELEASE and onward in the documentation
