Update OAuth2ClientAutoConfiguration in spring-grpc-server-spring-boot-autoconfigure

[vl4ds4m]

A Spring Boot grpc-server application can't start if it has 'spring-security-oauth2-client' dependency (without 'spring-boot-starter-security-oauth2-client'). The application requires OAuth2ClientProperties.java from 'spring-boot-starter-security-oauth2-client'.
To reproduces this problem, it's enough to create a demo project with Spring gRPC and 'spring-security-oauth2-client' by Spring Initializr and create a GrpcService bean. Spring Boot version: 4.0.2.

Good to know. Is there a reason you want to use spring-security-oauth2-client without the Boot starter? Seems like an error (and then we just need to make it easier to diagnose).

Yes, in my application I use a library that depends on spring-security-oauth2-client, and when I start the application Spring is trying to create OAuth2ClientAutoConfiguration.java from spring-grpc-server-spring-boot-autoconfigure because condition @ConditionalOnClass(InMemoryClientRegistrationRepository.class) is true, but it fails because of @EnableConfigurationProperties(OAuth2ClientProperties.class) (OAuth2ClientProperties.java from spring-boot-security-oauth2-client isn't on classpath).
