Description of changes:

Adding Corretto-21 images using the similar approach we did for 17 and 20. The difference from 20 is that we do not have al2023-generic.

Run the script locally to make sure it worked, the is an GHA to run it after you merge and add the comment on your commit.

bash bin/update-dockerfiles.sh
and
python3 bin/tag-generator.py | tee .tags
do not produce any errors

The corretto 21 images have not been published to official-images/amazoncorretto yet. We expect them to be available soon and we'll post an update here when they're ready.

official-images#15408 is the PR for the update. Once that's merged images should be available on dockerhub and ecr gallery within a few hours.
