DefaultSecretKeyVaultClient incorrectly instantiated when config-client is disabled

[nickmcdowall]

Expected Behavior

Simply adding a dependency on implementation("io.micronaut.azure:micronaut-azure-secret-manager")

and enabling eager initialisation of singleton beans at startup, i.e.

fun main(args: Array<String>) {
    build(*args)
        .eagerInitSingletons(true)
        .start()
}

we expect the app to continue to start up.

Actual Behaviour

We get a DependencyInjectionException when running the application in the local environment even though the config-client is disabled by default or explicitly, i.e.

micronaut:
  config-client:
    enabled: false

Error:

ERROR io.micronaut.runtime.Micronaut - Error starting Micronaut server: Bean definition [io.micronaut.azure.secretmanager.client.DefaultSecretKeyVaultClient] could not be loaded: Failed to inject value for parameter [client] of class: io.micronaut.azure.secretmanager.client.DefaultSecretKeyVaultClient

Message: No bean of type [com.azure.security.keyvault.secrets.SecretClient] exists. 
* [SecretClient] is disabled because:
 - Property [micronaut.config-client.enabled] with value [false] does not equal required value: true
Path Taken: new DefaultSecretKeyVaultClient(SecretClient client) --> new DefaultSecretKeyVaultClient([SecretClient client])
io.micronaut.context.exceptions.BeanInstantiationException: Bean definition [io.micronaut.azure.secretmanager.client.DefaultSecretKeyVaultClient] could not be loaded: Failed to inject value for parameter [client] of class: io.micronaut.azure.secretmanager.client.DefaultSecretKeyVaultClient

Upon inspection it looks like the following code might be the reason?:

Existing:

@Requires(classes = SecretClient.class)
public class DefaultSecretKeyVaultClient implements SecretKeyVaultClient {

Suggested change (look for beans not class on classpath):

@Requires(beans = SecretClient.class)
public class DefaultSecretKeyVaultClient implements SecretKeyVaultClient {

Steps To Reproduce

1. Clone example project
2. Run ./gradlew clean run

Worth highlighting that the issue appears only when the .eagerInitSingletons is enabled.
