[BUG] Spring presents Bean selection issues when passwordless and resource-manager are used together.

Maven：

<dependency>
    <groupId>com.azure.spring</groupId>
    <artifactId>spring-cloud-azure-dependencies</artifactId>
    <version>4.15.0</version>
    <type>pom</type>
    <scope>import</scope>
</dependency>
<dependency>
    <groupId>com.azure.spring</groupId>
    <artifactId>spring-cloud-azure-starter-jdbc-mysql</artifactId>

<dependency>
    <groupId>com.azure.spring</groupId>
    <artifactId>spring-cloud-azure-starter</artifactId>
</dependency>
<dependency>
    <groupId>com.azure.spring</groupId>
    <artifactId>spring-cloud-azure-resourcemanager</artifactId>
</dependency>

Properties：

# Database
spring.datasource.azure.passwordless-enabled=true
# ResourceManager
spring.cloud.azure.resource-manager.enabled=true

When I started springboot, I got the following error:

Parameter 0 of method azureResourceManager in com.azure.spring.cloud.autoconfigure.resourcemanager.AzureResourceManagerAutoConfiguration required a single bean, but 2 were found:
	- springCloudAzureDefaultCredential: defined by method 'tokenCredential' in class path resource [com/azure/spring/cloud/autoconfigure/context/AzureTokenCredentialAutoConfiguration.class]
	- passwordlessTokenCredential: defined in unknown location

I found in JdbcPropertiesBeanPostProcessor.class registered here TokenCredential.class.

private Map<String, String> buildEnhancedProperties(DatabaseType databaseType, AzureJdbcPasswordlessProperties properties) {
        Map<String, String> result = new HashMap<>();
        TokenCredentialProvider tokenCredentialProvider = TokenCredentialProvider.createDefault(new TokenCredentialProviderOptions(properties.toPasswordlessProperties()));
        TokenCredential tokenCredential = tokenCredentialProvider.get();

        AuthProperty.TOKEN_CREDENTIAL_BEAN_NAME.setProperty(result, PASSWORDLESS_TOKEN_CREDENTIAL_BEAN_NAME);
        applicationContext.registerBean(PASSWORDLESS_TOKEN_CREDENTIAL_BEAN_NAME, TokenCredential.class, () -> tokenCredential);

        LOGGER.debug("Add SpringTokenCredentialProvider as the default token credential provider.");
        AuthProperty.TOKEN_CREDENTIAL_PROVIDER_CLASS_NAME.setProperty(result, SPRING_TOKEN_CREDENTIAL_PROVIDER_CLASS_NAME);
        AuthProperty.AUTHORITY_HOST.setProperty(result, properties.getProfile().getEnvironment().getActiveDirectoryEndpoint());

        databaseType.setDefaultEnhancedProperties(result);

        return result;
    }

At the same time also registered a TokenCredential.class AzureTokenCredentialAutoConfiguration.class here.

    @ConditionalOnMissingBean(name = DEFAULT_TOKEN_CREDENTIAL_BEAN_NAME)
    @Bean(name = DEFAULT_TOKEN_CREDENTIAL_BEAN_NAME)
    @Order
    TokenCredential tokenCredential(DefaultAzureCredentialBuilderFactory factory,
                                    AzureTokenCredentialResolver resolver) {
        TokenCredential globalTokenCredential = resolver.resolve(this.identityClientProperties);
        if (globalTokenCredential != null) {
            return globalTokenCredential;
        } else {
            return factory.build().build();
        }
    }

So when AzureResourceManagerAutoConfiguration.class use TokenCredential.class, there is a mistake.

    @Bean
    @ConditionalOnMissingBean
    public AzureResourceManager azureResourceManager(TokenCredential tokenCredential, AzureProfile azureProfile) {
        // TODO (xiada) Do we need to pass our User-Agent to with the management sdk?
        // TODO (xiada) configure the http client of arm client
        return AzureResourceManager.configure().authenticate(tokenCredential, azureProfile).withDefaultSubscription();
    }

Does anyone know how to fix this? Thank you very much for your answer.
