[Feature] Presskit SVGs doesn't work well with non-white backgrounds

[jacobemcken]

Problem

Presskit SVGs don't work well with non-white backgrounds.

Current behavior on the left and desired behavior on the right.

Description

The SVGs used by the HTML produced by the "License chooser" have a solid white background inside the circle.
The icons are hosted here and are part of the "Presskit" e.g.:
https://mirrors.creativecommons.org/presskit/icons/by.svg

The white background icons from "Presskit" are inconsistent with the icons here (which are transparent):
https://github.com/creativecommons/vocabulary/tree/main/src/svg/cc/icons

I suggest having an extra set of icons in the "Presskit" with transparent centers.
It is probably a good idea to leave the current ones as is for backwards compatibility.
Maybe even use these in the "License chooser" by default moving forward.

Alternatives

Leave everything "as is", but having icons with transparent backgrounds available, we get a web that looks better 😅

Additional context

Maybe also provide SVGs with white "fill color" for dark (themed) websites.

Implementation

• I would be interested in implementing this feature. (but I would need some pointers as to where I can find this "Presskit")
