[css-images-4] image-set() format() typo? Should be type()?

[foolip]

https://w3c.github.io/csswg-drafts/css-images-4/#image-set-notation has this bit:

It does not have any effect on the image itself; an <image-set-option> like url("picture.png") 1x format("image/jpeg") is valid, and if chosen will display the linked PNG image, even though it was declared to be a JPEG.

Should that format("image/jpeg") be type("image/jpeg"), matching the syntax?

Reported in #7388.

OK, sent #7806 to fix it.
