Starting from Spring Boot 4, the RestTemplateBuilder and
RestTemplateCustomizer classes have been moved from the
org.springframework.boot.web.client package to the
org.springframework.boot.restclient package. This commit updates
the javadoc links in the reference documentation to match

Previously, spring-boot-restclient was a required dependency of
spring-boot-resttestclient. This had the unwanted side-effect of
increasing the risk of the test classpath enabling auto-configuration
for RestClient.Builder when it was main code that needed such a bean.
This could lead to integration tests passing but the application
itself failing to start when its run through its main method.
This commit makes spring-boot-restclient an optional dependency of
spring-boot-resttestclient. As a result, a dependency on
spring-boot-resttestclient is no longer sufficient to auto-configure
a RestClient.Builder bean, although it is still sufficient to
auto-configure a RestTestClient bean.
Those that wish to use TestRestTemplate rather than migrating to
RestTestClient will now have to add a dependency on
spring-boot-restclient. This makes it presence more obvious. It now
has to be declared directly rather than being somewhat hidden due to
being pulled in transitively. The hope is that this will reduce the
chances of the dependency being accidentially on the test classpath
when main code requires it to be on the runtime classpath.
Fixes gh-48253
Change `spring-boot-tomcat-runtime` and `spring-boot-jetty-runtime`
into starter POMs and reduce the number of dependencies needed for
`spring-boot-tomcat` and `spring-boot-jetty`.
The runtime starters provide only the jars required to run the
embedded server along with the module jar itself (excluding transitive
dependencies) and `spring-boot-webserver` (excluding transitive
dependencies).
The build setup required for an executable jar is slightly different
between Maven and Gradle. For Maven, the regular module is put in the
`provided` scope. For Gradle, the regular module remains in main
configuration and the runtime jar is put in the `providedRuntime`
configuration. The reference documentation has been updated to
show how to configure things if starters are being used.
Manual testing has been performed to ensure that wars build with Maven
and Gradle work with both Tomcat and Jetty in both deployed and
`java -jar` modes.
