Describe the bug

When I generate the code with the v1.18.0 I encountered a generation error.
My service is called ExampleV1beta1, but when I generate the code with buf I have found an error as the generated code is

exampleV1beta1Methods :=  example.File_redcarbon_example_example_proto.Services().ByName("ExampleV1beta1").Methods()
	return &exampleV1Beta1Client{
		getExample: connect.NewClient[example.GetExampleRequest, example.GetExampleResponse](
			httpClient,
			baseURL+ExampleV1Beta1GetExampleProcedure,
			connect.WithSchema(exampleV1Beta1Methods.ByName("GetExample")),
			connect.WithClientOptions(opts...),
		),
	}

As you can see the variable is exampleV1beta1Methods but is used inside of the function as exampleV1Beta1Methods.

To Reproduce

I have used the following buf.gen.yaml

version: v1
managed:
  enabled: true
  go_package_prefix:
    default: pkg.redcarbon.ai/proto
plugins:
  - plugin: buf.build/protocolbuffers/go:v1.36.0
    out: proto
    opt: paths=source_relative
  - plugin: buf.build/connectrpc/go:v1.18.0
    out: proto
    opt: paths=source_relative

the service is

syntax = "proto3";

package example;

service ExampleV1beta1 {
  rpc GetExample(GetExampleRequest) returns (GetExampleResponse) {}
}

message GetExampleRequest {
  string example_id = 1;
}

message GetExampleResponse {
  string example_id = 1;
  string example_name = 2;
}
