As part of the [Javascript Inline Docs Initiative](https://make.wordpress.org/core/handbook/docs/inline/js/) this add some tooling to lint Javascript docblocks. Two new commands:
* `npm run lint:jsdoc`
* `npm run lint:jsdoc:fix`
The latter will run the linter and try to fix an possible issues automatically.
Fixes#43828.
