E2E Test: Fix and update release testing

[majanjua-amzn]

Change log:

• Fixing release testing by updating the override to work with EKS addon
• Updating test to use enablement script from aws-observability/application-signals-demo
• Added API calls before test run to speed up test like in other repos
• Removed caller-workflow-name input
• Pull test resources from aws-observability/aws-otel-java-instrumentation to remove code duplication
• Updating some of the versions for actions like checkout to better match the workflow in the ADOT repo
• Updated the image verification steps to show the operator image that is being used in the pods
• Updated the image verification steps to fail if the operator image did not change after patching

The change to patch the deployment is based on template defined here: link

Test fails if image hasn't changed: run
Test passes if image is changed to a functional one: run
