Fix documentation inconsistencies

[doehyunbaek]

I found five documentation issues that still appear to be present on current main as of f71e797.

1. RestTemplateBuilder docs reference deprecated rootUri API

The @RestClientTest documentation still describes RestTemplateBuilder.rootUri(String) behavior:

spring-boot/documentation/spring-boot-docs/src/docs/antora/modules/reference/pages/testing/spring-boot-applications.adoc

Lines 743 to 747 in f71e797

	When using a javadoc:org.springframework.boot.restclient.RestTemplateBuilder[] in the beans under test and `RestTemplateBuilder.rootUri(String rootUri)` has been called when building the javadoc:org.springframework.web.client.RestTemplate[], then the root URI should be omitted from the javadoc:org.springframework.test.web.client.MockRestServiceServer[] expectations as shown in the following example:
	include-code::MyRestTemplateServiceTests[]
	When using a javadoc:org.springframework.web.client.RestClient$Builder[] in the beans under test, or when using a javadoc:org.springframework.boot.restclient.RestTemplateBuilder[] without calling `rootUri(String rootURI)`, the full URI must be used in the javadoc:org.springframework.test.web.client.MockRestServiceServer[] expectations as shown in the following example:

But RestTemplateBuilder.rootUri(String) is deprecated in favor of RestTemplateBuilder.baseUri(String):

2. LiveReload is documented as deprecated in one place but active elsewhere

The devtools reference documentation marks LiveReload as deprecated:

spring-boot/documentation/spring-boot-docs/src/docs/antora/modules/reference/pages/using/devtools.adoc

Line 285 in f71e797

WARNING: Given its decrease in popularity and support, the LiveReload feature is deprecated as of Spring Boot 4.1.0 with no replacement.

But the Maven plugin and hotswapping documentation still present LiveReload as an active devtools feature without mentioning its deprecation:

3. RabbitMQ Streams docs mention only the non-SSL port

The service connection docs state that RabbitMQ Streams containers need port 5552 exposed:

• spring-boot/documentation/spring-boot-docs/src/docs/antora/modules/reference/pages/features/dev-services.adoc

  Lines 131 to 132 in f71e797

  	| javadoc:org.springframework.boot.amqp.autoconfigure.RabbitStreamConnectionDetails[]
  	| Containers named "rabbitmq" with container port 5552 mapped

But when SSL is configured, the connection details code uses port 5551:

4. Log4j2 rotation docs contain a typo

The logging documentation says Logback of Log4J2:

spring-boot/documentation/spring-boot-docs/src/docs/antora/modules/reference/pages/features/logging.adoc

Line 218 in f71e797

If you are using Logback of Log4J2, it is possible to fine-tune log rotation settings using your `application.properties` or `application.yaml` file.

This should be Logback or Log4j2.

5. OAuth2 provider documentation omits x

OAuth2ClientProperties documents the common OAuth2 providers as google, github, facebook, and okta:

spring-boot/module/spring-boot-security-oauth2-client/src/main/java/org/springframework/boot/security/oauth2/client/autoconfigure/OAuth2ClientProperties.java

Lines 81 to 82 in f71e797

	* Reference to the OAuth 2.0 provider to use. May reference one of the common
	* providers (google, github, facebook, okta) or the ID of a custom provider

But Spring Security 7.1.0's CommonOAuth2Provider also includes X:

https://github.com/spring-projects/spring-security/blob/7.1.0/config/src/main/java/org/springframework/security/config/oauth2/client/CommonOAuth2Provider.java#L91-L102

This PR fixes the above five issues.

Thanks very much, @doehyunbaek. Of the 6 inconsistencies, 5 apply to main but one (number 5) applies to 4.0.x and main. Would you mind dropping 5 (commit a35391b) from this PR and opening a new PR for that change which uses 4.0.x as its base branch?

[doehyunbaek]

Hi @wilkinsona. I opened a separate PR #50842 and made this PR contain only five commits bound to main. I'm not super confident I did everything right but hope I didn't mess up!

Thank you very much for reviewing my PR.

[wilkinsona]

You didn't mess up at all. Thanks very much for doing that and for the PR in general. Much appreciated.
