Update ddapm-test-agent docker image to v1.63.0

[AlexeyKuznetsov-DD]

What Does This Do

Bumps the ddapm-test-agent docker image to v1.63.0 in all places where it is declared:

• utils/_context/containers.py — APMTestAgentContainer (was v1.31.1) and VCRCassettesContainer (was v1.62.0)
• utils/_context/_scenarios/parametric.py (was v1.62.0)
• utils/_context/_scenarios/integration_frameworks.py (was v1.62.0)
• utils/k8s_lib_injection/k8s_datadog_kubernetes.py (was v1.31.1)

Motivation

Keep the test-agent container up to date so scenarios run against the latest agent behavior and validation logic.

Additional Notes

• The ddapm-test-agent==1.18.0 pip pin in requirements.txt is intentionally left untouched — it only provides the Span/Trace type imports for the harness and is versioned/updated independently of the container image.
