... rather than just the category id.
In order for the user to have selected a category, the category must
have been loaded and it's useful for the category chooser to provide
this fetched category so that it doesn't need to be refetched.
In the future, it would be better to store the categories that the
chooser knows about in local component state, so that the category
doesn't need to be fetched from the id map, but this, at least, puts the
API in place.
Follow-up to #24278 that is slightly less trivial.
* Some were "trivial" usages that were missed in the previous PR because the same file that had at least one other non-trivial usage.
* These involve extra arguments or inheritance but I have checked that they seem correct.
1. Use `this.` instead of `{{action}}` where applicable
2. Use `{{fn}}` instead of `@actionParam` where applicable
3. Use non-`@` versions of class/type/tabindex/aria-controls/aria-expanded
4. Remove `btn` class (it's added automatically to all DButtons)
5. Remove `type="button"` (it's the default)
6. Use `concat-class` helper

deprecates the class_name field from EmbeddableHost and suggests using
the className parameter. discourse_username parameter has been
deprecated and it will fetch it from embedded site from the author or
discourse-username meta.
See the updated code sample from Admin > Customize > Embedding page.
