[Bug][http-client-js] When an Enum has a value of 0, the output value is missing in http-client-js

[sho-pb]

Describe the bug

An Enum with a value of "0" is defined as shown below:

enum TestEnum {
  Key1: 0,
  Key2: 1,
}

model Widget {
  id: string;
  weight: int32;
  color: "red" | "blue";
  testEnum: TestEnum;
}

When this is compiled with http-client-js, the Enum output in the generated models will be missing the value 0, as shown below:

export enum TestEnum {
  Key1 = , // 0 is missing
  Key2 = 1
}

Appears to be fixed in main as a result of this Alloy change: alloy-framework/alloy#72.

@sho-pb, could you try using 0.4.0 of @typespec/http-client-js and let us know if the issue persists?

Confirmed, the enum type looks good now. Thanks for the quick fix! 🙇
