[dnijssen]

Describe the bug
Between Spring Cloud Azure Dependencies 6.0.0 -> 6.1.0 we stumbled upon a ClassNotFoundException: com.nimbusds.oauth2.sdk.util.StringUtils

Exception or Stack Trace

Caused by: java.lang.NoClassDefFoundError: com/nimbusds/oauth2/sdk/util/StringUtils
	at com.azure.spring.cloud.autoconfigure.implementation.aad.security.properties.AadAuthorizationServerEndpoints.<init>

Additional context
We just have a simple Spring Boot project at our side, with the following Security related dependencies;

implementation("org.springframework.boot:spring-boot-starter-security")
implementation("org.springframework.boot:spring-boot-starter-oauth2-resource-server")
implementation("com.azure.spring:spring-cloud-azure-starter-active-directory")

Works with Spring Boot 3.5.9 and Spring Azure Cloud Depenencies 6.0.0, but when upgrading to Spring Azure Cloud Dependencies 6.1.0 it breaks
