gRPC version is out of sync in readme documentation, causing `NAME_RESOLUTION_DELAYED` errors #52

The problem

When pulling in the library versions described in the README.md file, trying to make rpcs will result in errors that look like the following:

java.lang.NoSuchFieldError: NAME_RESOLUTION_DELAYED

Steps to reproduce

  1. Pull in these dependencies 
    dependencies {
implementation "com.authzed.api:authzed:0.5.0"
implementation 'io.grpc:grpc-protobuf:1.54.1'
implementation 'io.grpc:grpc-stub:1.54.1'
}
  2. Make a CheckPermissionRequest rpc

Solution

Update the README.md to point to the grpc version in https://github.com/authzed/authzed-java/blob/main/build.gradle#L80-L97 from the above to the following:

dependencies {
    implementation "com.authzed.api:authzed:0.5.0"
    implementation 'io.grpc:grpc-protobuf:1.55.1'
    implementation 'io.grpc:grpc-stub:1.55.1'
}
