Stéphane Nicoll 3959c56bdd Deprecate RestTemplate support ...

With Spring Framework 7.1 deprecating RestTemplate for removal, this
commit deprecates our supporting infrastructure as well, and steers
users towards RestClient instead:

* RestTemplateAutoConfiguration and
  RestTemplateObservationAutoConfiguration
* RestTemplateBuilder, RestTemplateBuilderConfigurer, and
  RestTemplateBuilderClientHttpRequestInitializer
* RestTemplateCustomizer, RestTemplateRequestCustomizer, and
  ObservationRestTemplateCustomizer
* MockRestServiceServerAutoConfiguration,
  MockServerRestTemplateCustomizer, and RootUriRequestExpectationManager
  in the test support module

The reference documentation no longer covers RestTemplate and now
solely documents RestClient and WebClient. Code snippets and sample
tests that only existed to illustrate RestTemplate usage have been
removed accordingly.

Closes gh-51118
