URLs instead of IDs

As I'm sure you know, assets IDs were replaced by URLs in v2.5.0.

FYI: This works perfectly for my usecase - thanks you for sharing it:
- Portfolio site with a global grid field to allow client to add their social media channels
- Grid has an asset field to set an SVG file
- Need to inline the SVG in order to style with CSS (fill colour changes depending on context)
