Sigv4 - Add Missing STS Dependency (#1101)

*Issue #, if available:*
Current Sigv4 Exporter is missing the required dependency from AWS SDK
library to allow STS AssumeRole from the DefaultCredentialsProvider.

For example, this is the error that pops up if the exporter is used in
an EKS environment:
``` WebIdentityTokenCredentialsProvider(): To use web identity tokens, the 'sts' service module must be on the class path. ```

Leading to the credentials provider to default to the worker node role:

```
WARN io.opentelemetry.exporter.internal.http.HttpExporter - Failed to
export spans. Server responded with HTTP status code 403. Error message:
User:
arn:aws:sts::571600841604:assumed-role/eksctl-spring-demo-cluster-nodegro-NodeInstanceRole-qe5bSShjEHDp/i-0e398f24217b99394
is not authorized to perform: xray:PutTraceSegments because no
identity-based policy allows the xray:PutTraceSegments action
 ```

*Description of changes:*

Add STS as a dependency for the OtlpAws Exporters in order to allow the
exporter to AssumeRole.
- Bumping dependency to 2.30.17 as that is the version that a major CVE
was patched in AWS SDK v2:
aws/aws-sdk-java-v2#6098

*Testing*
A sample EKS application was deployed with a custom ADOT Java Agent
artifact that has the STS dependency added. I see spans appearing in the
```aws/spans``` log group:
