fix(concatjs): resolve error with TypeScript 5.0

In the concatjs `CompilerHost.resolveTypeReferenceDirectives` method the `undefined` values are excluded, despite the return value being `(ts.ResolvedTypeReferenceDirective|undefined)[]`. Until now TS was handling this gracefully, but it appears to trigger an error after 5.0.

These changes add some code that should be both backwards and forwards compatible.
