cleanup-acr-images pipeline is timing out due to running for over 1 hour

Example pipeline run: https://dev.azure.com/dnceng/internal/_build/results?buildId=2803659&view=logs&j=e8cc81cf-26b4-5f33-a1eb-f3b806c49728&t=b9af4dd4-b77b-5e11-affd-95329117aefd

Long-running steps:

• Generate EOL Annotations: 42 minutes
• Generate EOL Annotations: 13 minutes (timed out)

[Triage] We should increase the timeout on the EOL annotations job in the cleanup-acr-images pipeline - Doubling the timeout to 2 hours is a good first step.
