This is for use in the folder permissions UI. It’s designed to be sized
at the same width as a GOV.UK style checkbox. The CSS to render it is
something like:
```css
background-image: file-url('folder-black.svg');
background-repeat: no-repeat;
background-size: 39px auto;
background-position: 0px 4px;
```
After showing this to a few people the consensus seems to be that
‘Templates’ isn’t itself a folder. Therefore it shouldn’t have a folder
icon.
This has the advantage of disambiguating between being in a folder:
> [screenshot]
…and being in a subfolder:
> [screenshot]
These are copied from the prototype but with the following changes:
- redrawn to snap exactly to pixels
- slightly thicker border for the blue version, and a thinner border for
the black version, so they look better in situ
- run through https://jakearchibald.github.io/svgomg/ for optimal file
size
This commit doesn’t do anything with the images yet, it just adds them
to the repo.
