Expose StatementRangeSyntaxError via hooksAPI()

This is why I was needing `'positron'` as an "external" before. We've never had to expose a class that we need to construct before, and it requires using it as a "value" rather than just as a "type" so it needs to show up in `PositronApi` and be called via `hooksApi()`
