feat(deps): update OpenTelemetry version to 2.15.0

[rafaelsmf]

Description:

This PR addresses an issue with the OpenTelemetry version 2.11 used in the project.

After integrating DataHub with the Datadog agent, I noticed that the Datadog agent was no longer able to link to the application's components. This issue started occurring following the OpenTelemetry upgrade to version 2.11 introduced in DataHub version 1.0.0.

See the screencast below for reference:

How It Was Fixed:

This issue was resolved in OpenTelemetry version 2.12 and above.

In this PR, I've upgraded the OpenTelemetry dependency to version 2.15.0, which resolves the compatibility issue with the Datadog agent.

Testing:

The fix has been tested across multiple environments to ensure robustness:

• Local Testing:

Verified that the OpenTelemetry upgrade to 2.15.0 works as expected in a local development environment.

• Docker Testing:

Deployed the updated setup in a Docker container to validate configuration and functionality.

• Kubernetes Testing:

Confirmed that the application and telemetry exporters function correctly within a Kubernetes environment.

• Datadog Agent:

Validated that metrics and traces are successfully sent to Datadog using the upgraded OpenTelemetry version (datadog agent version 7.50.3+).
