Spring Cloud GCP Starter Secret Manager - Failed to create the Secret Manager Client for ConfigData loading

Hi there, I'm having problems with my spring boot application using gcp secret manager. Found this comment on a closed issue [#1628](https://github.com/GoogleCloudPlatform/spring-cloud-gcp/issues/1628) where the author was asked to create a new issue on it, but I didn't find any issues created. I'm having the same issues as the original poster with spring boot 3.1.0 and secret manager 4.3.1.

Here is the original comment:

Hi there, i have similar problem and i am curious what i am doing wrong.
Here is my setup...

In the pom.xml i have the following
```

org.springframework.boot
spring-boot-starter-parent
3.0.2

```

```

com.google.cloud
spring-cloud-gcp-dependencies
4.1.4
pom
import

```
```

com.google.cloud
spring-cloud-gcp-starter-secretmanager

```

In the application.properties I have added a property like so: my.app.secret=${sm://test_secret}.

Now in the code i tried a couple of things:
1. @Value("${sm://test_secret}")
private String secret;
2. System.out.println(env.getProperty("my.app.secret"));
3. @Autowired
private SecretManagerTemplate secretManagerTemplate;

secretManagerTemplate.getSecretString("test_secret");


From the above 1. and 2. are returning '//test_secret' and not the value of the secret.
3. Is returning properly the value of the secret.

Based on this thread I tried putting 'spring.config.import=sm://' in my application.properties file, but this is breaking my application:
