chore: add light logo for Github README view

[astone123]

Closes #1402

We're using rwa-logo.svg for our logo in the readme, which uses the currentColor attribute for its fill color, which should allow the fill to change with the context of where it is placed. It appears that this isn't working correctly in Github when it displays the README.

To fix this, I created rwa-logo-light.svg which explicitly sets the fill colors to white, and added the suffixes that Github will use to display each SVG depending on whether the user is in light mode or dark mode.

The downside to this approach is that some previewers (like the VSCode preview) do handle this correctly, so now they'll show two images side-by-side. I think it's worth the tradeoff to look better on Github though.

Github light mode

Github dark mode
