chore(codebuild): aarch64 standard 2.0 and 3.0 build images are not deprecated (#29580)

### Issue # (if applicable)

Closes #<issue number here>.

### Reason for this change



AWS CodeBuild Docker images `AMAZON_LINUX_2_ARM_3` aka `AMAZON_LINUX_2_STANDARD_3_0` aka `aws/codebuild/amazonlinux2-aarch64-standard:3.0` and `AMAZON_LINUX_2_ARM_2` aka `AMAZON_LINUX_2_STANDARD_2_0` aka `aws/codebuild/amazonlinux2-aarch64-standard:2.0`are not deprecated but the currently actively maintained ones according to https://github.com/aws/aws-codebuild-docker-images and https://docs.aws.amazon.com/codebuild/latest/userguide/build-env-ref-available.html

### Description of changes



I removed the JSDoc Deprecated flag for the currently active images and added their image names as a comment so that one can find the images also using those references.
