[ruby/prism] Fix defined with new line

It's possible to write the following and have it be valid Ruby:

```
defined?("foo"
)
```

But Prism wasn't taking the new line into account. This adds an
`accept1` for a `PM_TOKEN_NEWLINE` to account for this. I've also
updated the fixtures and snapshots to test this.
