 * which doesn't allow us to create a list of {@link PropertySource} manually (facepalm). So if we want to explicitly
 * tell Spring's {@link PropertySourcesPlaceholderConfigurer} which property sources it can use (e.g. because the
 * default list isn't enough), AND we want to keep reading env variables, we can use this implementation.
