Revs:

• Move operator build to Github runner by syncing Makefile and Dockerfile with the upstream
• Drop all hacky changes since they are not needed anymore

Build and deploy test run: https://github.com/aws/amazon-cloudwatch-agent-operator/actions/runs/13055448538

--

• Use ubuntu:latest for TargetAllocator certificates to make it consistent with CWA
• Drop date change for TargetAllocator

Build is failing due to expired certificate with opencensus and not being able to fetch alpine for certs

Example error:

// cert
