PUBLIC_URL Is No Longer Supported

If you are using {{PUBLIC_URL}} in a site plugin extension's plugin.json, you will get the following error when you attempt to build you app:

What to do

1. Move all files from /public to src/assets.
2. Update the value of logoUrl in your plugin.json to reflect the new relative path from the plugin.json to the logo file in src/assets.
3. Commit and save your changes.
