Fix missing comma in @_expose attribute for SwiftSyntax602

The SwiftSyntax602 code path in `buildExposeAttributes` was using array
literal syntax to construct `LabeledExprListSyntax`, which doesn't set
`trailingComma` on the AST nodes. This resulted in malformed attributes:
`@_expose(wasm "name")` instead of `@_expose(wasm, "name")`.

The fix uses the result builder syntax with explicit `.with(\.trailingComma,
.commaToken())` to ensure the comma is present in the generated code.

Also adds a dedicated `bridgejs-test` CI job that tests BridgeJS with
multiple Swift/SwiftSyntax version combinations to ensure both code paths
(pre-602 and 602+) are exercised:
- Swift 6.0.3 with SwiftSyntax 600.0.1
- Swift 6.1.2 with SwiftSyntax 601.0.1
- Swift 6.2 with SwiftSyntax 602.0.0
