fix(decorator): replace hard code url with {endpoint} in @scenarioService

[archerzz]

Hard coded value should be replaced by a parameter, like #425

fix #597

Cadl Ranch Contribution Checklist:

• I have written a scenario spec
• I have meaningful @scenario names. Someone can look at the list of scenarios and understand what I'm covering.
• I have written a mock API
• I have used @scenarioDocs for extra scenario description and to tell people how to pass my mock api check.

Any other language need this?

For Java, this change means we need to update all the client in test (probably on the hundreds) to set endpoint=localhost:3000

I believe dotnet is not using localhost:3000: https://github.com/Azure/autorest.csharp/blob/9790814dd86eb1279e5c98fd123e4bcea7456553/test/CadlRanchProjects.Tests/type-enum-fixed.cs#L14-L18

But dotnet allows users to override the host, even if it's explicitly specified in spec. Things could be different in other languages. We can hold this PR for further discussion.

LGTM, can we make its default value as "http://localhost:3000" so that it won't break others.

I don't think we can, because currently there's no way to set client side default value in typespec.

for endpoint, tcgc will treat service default as client default. this is the only exception. mpg template also has such pattern. @archerzz could you help to refine it?

I see :-)

Yeah, if we all take the service default of "host" as client default, I am good with this PR, as long as it have localhost as default of the endpoint.

[archerzz]

Please hold this PR. After discussion, we decided to inject the following:

@server(
  "{endpoint}",
  "Test server endpoint",
  {
    endpoint: string = "http://localhost:3000",
  }
)
