[css-images-4] `<linear-gradient>` and `<radial-gradient>` links point to CSS Images Module Level 3

[nchevobbe]

In https://drafts.csswg.org/css-images-4/#typedef-gradient:~:text=%3Clinear%2Dgradient%28%29%3E&text=%3Cradial%2Dgradient%28%29%3E the <linear-gradient> and <radial-gradient> links are respectively pointing to https://drafts.csswg.org/css-images-3/#funcdef-linear-gradient and https://drafts.csswg.org/css-images-3/#funcdef-radial-gradient

I would expect them to link to https://drafts.csswg.org/css-images-4/#linear-gradients and https://drafts.csswg.org/css-images-4/#radial-gradients

I believe this is technically correct. Images 3 defines

<linear-gradient()> = linear-gradient( [ <linear-gradient-syntax> ] )

and Images 4 redefines <linear-gradient-syntax>

On the other hand it might well be clearer to just redefine <linear-gradient> in images 4; after all it already copies over <side-or-corner> unchanged..

@tabatkins @fantasai @LeaVerou what do you think?
