docs: Overrides Spring Boot's {@link FreeMarkerAutoConfiguration} to prefer using a
  {@link SpringTemplateLoader} instead of the file system. This corrects an issue
  where Spring Boot may use an empty 'templates' file resource to resolve templates
  instead of the packaged Hystrix classpath templates.
