chore: update Manifest Server to use Python 3.13

[dbgold17]

After several PRs to remove problematic CDK dependencies, update the Manifest Server to use Python 3.13

resolves: https://github.com/airbytehq/airbyte-internal-issues/issues/14878

Testing

• I published a pre-release manifest-server image and referenced it here on my local airbyte-platform-internal repo. Then I built the platform with make dev.up.oss and verified I could use the Connector Builder.

Summary by CodeRabbit

• Chores
  • Upgraded container runtime environment to Python 3.13.9 for improved stability and performance.
  • Added explicit image digest to ensure reproducible and verifiable deployments.
