[java-bigtable] BigTable API - Error connecting to BigTable Emulator

Can you please help me identify why BigTable API fails to connect with BigTable emulator running on Docker?

#### Environment details

1. Specify the API at the beginning of the title - **BigTable**
2. OS type and version: Mac
3. Java version: 17
4. bigtable version(s): Docker BigTable

#### Steps to reproduce

1. Start gcloud BigTable emulator in local Docker.
2. Run the basic Read example - https://github.com/googleapis/java-bigtable/blob/main/samples/snippets/src/main/java/com/example/bigtable/Reads.java

#### Code example

```pom.xml



com.google.cloud
libraries-bom
26.37.0
pom
import

......


.....

com.google.cloud
google-cloud-bigtable

```
```java
try (BigtableTableAdminClient adminClient =
BigtableTableAdminClient.create(projectId, instanceId)) {
CreateTableRequest createTableRequest =
CreateTableRequest.of(tableId)
.addFamily(COLUMN_FAMILY_NAME_STATS)
.addFamily(COLUMN_FAMILY_NAME_PLAN);
adminClient.createTable(createTableRequest);
} catch (IOException e) {
System.out.println("Error during createTable: \n" + e.toString());
throw (e);
}
```

#### Stack trace
```

Inspect pom.xml and the sample entry point at samples/snippets/src/main/java/com/example/bigtable/Reads.java, then run the example against the Docker Bigtable emulator. Start with the BigtableTableAdminSettings stack-trace entry and verify the dependency setup. Done means the sample connects and reaches table creation without the reported NoClassDefFoundError.
