0ko da12320a0c Replace imgage diff png background pattern with gradient (#3870)
Made the checkerboard background be more flexible in terms of scale and coloring. Provides dark theme for image diff.

I suppose these colors should not be re-used for a color-picker for a example, because it's usually more convenient to always have it in the light mode.

## Test

* go to e6d3623c7e
* or migrate https://next.forgejo.org/image-test/image-diff to your local instance

## Before/after
