Plugin API should include assets for available updates

[swissspidy]

As mentioned in #1579 and ​#wp30186 it would be great if the plugin updates API would include the URLs to a plugin's icon and perhaps the banner as well.

This would pave the way for an improved plugin list table and list of available updates.

Ideally, we could roll this out together with Shiny Updates V2, where we already show icons for all other available updates, just not for plugins.

The update API now returns arrays of icons and banners, when available.

(As of ~15 minutes from this post, when the cache expires.)

@pento It doesn't look like the API returns default icons (the randomized SVG ones) when there is none.

The SVG is generated inline in the w.org HTML, there isn't an image URL to refer to.

If there isn't an icon provided in the API response, the app (including WordPress) should use a local icon.

Hmm, the regular plugins API does send the SVG though. AFAIK the GeoPattern library isn't part of core and we'd need to include it to have the default icons match the ones from w.org

[pento]

Not that easy, unfortunately. The GeoPattern code really doesn't like being run outside of the context of the plugin directory plugin, and the update-check API isn't even close to being able to run that.
