GatewayRouterFunctions.uri is no more

Describe the bug
i need a forward proxy and thought i'd setup spring-cloud-gateway to fix that for me;

https://github.com/spring-cloud/spring-cloud-gateway/blob/v4.2.2/docs/modules/ROOT/pages/spring-cloud-gateway-server-mvc/java-routes-api.adoc#gateway-mvc-implementation-of-routerfunctionsbuilder

The docs here yield non-compiling code

versions

• spring-cloud.version 2024.0.1
• spring-cloud-gateway-server-mvc 4.2.1

	@Bean
	public RouterFunction<ServerResponse> getRoute() {
		return route("simple_route").GET("/info.0.json", http())
				.before(uri("https://xkcd.com"))
				.build();
	}

the uri method is not in GatewayRouterFunctions so docs are a bit off and i'm happy to fix that but i the code isn't clear on where it went :)

this yaml in config works and does what i want

spring:
  cloud:
    gateway:
      mvc:
        routes:
          - id: xkdc_route
            uri: https://xkcd.com
            predicates:
              - Path=/info.0.json

or see full demo project: proxy-foward.zip

tnx; happy to contribute any docs update(s) or other changes :)

Start with docs/modules/ROOT/pages/spring-cloud-gateway-server-mvc/java-routes-api.adoc and the GatewayRouterFunctions reference used by its example. Compare the documented Java route with the working YAML configuration and the supplied demo project to identify the current API. Done means the documentation uses a compiling example for the stated Spring Cloud Gateway versions and explains the applicable replacement or configuration.
