[Bug]: SdkEndpointParamter.clientDefaultValue should have value

[archerzz]

Describe the bug

SdkEndpointParameter extends SdkModelPropertyBase which has clientDefaultValue which should have value for SdkEndpointParameter (like http://localhost:3000). Right now, the value is in SdkEndpointParameter.type.serverUrl

Reproduction

Parse a typespec spec, check the SdkEndpointParameter value

this information is not on the SdkEndpointParameter itself, because we have made our design work fro both templated and non-templated endpoints. Instead, this information is in templateArgs, where if ther's a .clientDefaultValue, that information would be in the template arguments. Closing because this is by design
