[Bug]: The code snippet for union is ambiguous in TypeSpec extension.

[lirenhe]

Describe the bug

I got the following when I tried the code snippet for union

union Name = variant1 | variant2;

It is ambiguous as in https://typespec.io/docs/language-basics/unions/.

we could either define it as expression

alias Breed = Beagle | GermanShepherd | GoldenRetriever;

or as named union

union Breed {
  beagle: Beagle,
  shepherd: GermanShepherd,
  retriever: GoldenRetriever,
}

The code snippet seems to be a mix of the above.

Reproduction

As described above
