gen-aem-aws-stack-builder-ami-ids doesn't work for different JDK8 and JDK11

[ovlords]

The 'make gen-aem-aws-stack-builder-ami-ids' populates the same AMIs for JDK8 and JDK11 variants of the profiles. It should be different.

Please also test it to make sure it gets the ami-ids from all component types. I noticed it wasn't finding the ami_id for the Author-Publish-Dispatcher component.

There is no amis for redhat JDK8 and JDK 11. Please bake them and try it again.

The issue with not finding AMI ID for Author Publish Dispatcher was caused by inexisting AMIs which then causes the value to be set as null. @rJunx has baked the AMIs and the null values have been replaced, e.g. https://github.com/shinesolutions/aem-helloworld-config/pull/52/files#diff-53f9ab841316df5620a4fd3365b5cf8fce3cbafdc55f47fbf9a4d794356bfcb4L7
