This is a small PR that adds a `.jsdoc` scope to JSDoc tokens, just like [JSX](https://github.com/zed-industries/zed/blob/d95a7fe27c2941350f042a63a1ce73bd9a550047/crates/languages/src/javascript/highlights.scm#L239) has a specific scope. This effectively allows differentiating between JavaScript keywords and JSDoc tags in comments. Release Notes: - Add scope for JSDoc
