`*` in an array pattern should not be parsed as nil in ripper

2023-04-01T07:35:24+00:00

After 6c0925ba7017efde6091e2ec4f1a6be268166696, it was impossible
to distinguish between the presence or absence of `*`.

    # Before the commit
    Ripper.sexp('0 in []')[1][0][2][1]  #=> [:aryptn, nil, nil, nil, nil]
    Ripper.sexp('0 in [*]')[1][0][2][1] #=> [:aryptn, nil, nil, [:var_field, nil], nil]

    # After the commit
    Ripper.sexp('0 in []')[1][0][2][1]  #=> [:aryptn, nil, nil, nil, nil]
    Ripper.sexp('0 in [*]')[1][0][2][1] #=> [:aryptn, nil, nil, nil, nil]

The difference from 0b8c73aa65add5c57b46b0cfdf4e661508802172 is to
add the result of `string_add` event to marking objects.

```C
			    RNODE($1)->nd_rval = add_mark_object(p, $$);
```
