Re: [csswg-drafts] [css-ui-4][css-images-4] `<string>` in `<image-set()>` and `<url-set>` (#7388)

> If it's not currently written as such, that's a spec bug.

Given these productions:

```
<image-set()> = image-set(<image-set-option>#) 
<image-set-option> = [<image> | <string>] [<resolution> || type(<string>)]
<image> = <url> | <image()> | <image-set()> | <cross-fade()> | <element()> | <gradient>
```

I suggest this change:

```diff
- `<url-set>` is a limited version of image-set(), where only `<url>` and `<url-set>` can be used in the part of the `<image-set-option>` sub-production which would normally allow `<image>`.
+ `<url-set>` is a limited version of image-set(), where only `<url>` and `<url-set>` can be used in the part of the `<image>` sub-production.
```
