Encoding.Copy not copy annotation of methods#1652

Hi, i have an Encoding class with a method like this.

@Encoding.Naming("with*OrNull")
@Encoding.Copy
public Possible<Optional<T>> withOrNull(@Nullable T value) {
      return discord4j.discordjson.possible.Possible.of(Optional.ofNullable(value)); //Posible its like an Optional for internal
}

the issue is every class generated with that not include the Nullable from JSpecify

public Builder optionalOrNull(String value) { // not annotation here
      this.optional_possible = Possible.of(Optional.ofNullable(value));
      return this;
}

this cause a few warnings in IDE or mess with kotlin nullability checkers for the use of @NullMarked

    Thank you for reporting this. I don't know if it were ever designed or implemented to copy annotations. This definitely predates any TYPE_USE annotations. I'll see if that can be implemented, but cannot promise that would be soon.

    Has this been solved by #1671 ? If so, is there a published version with that fix?
