Changelog for new images

Hey, is there any place where I could see some release notes for new image tag pushes?

There is https://gallery.ecr.aws/lambda/nodejs which lists the tags pushed, but with no more info.

This repo is force-pushed and at least for nodejs18.x only contains [bunch of tarballs](https://github.com/aws/aws-lambda-base-images/tree/nodejs18.x/x86_64) - so it's pretty much impossible to see what changed with new images.

There was a few new tags pushed every week now, would be useful to see what is actually changed - so I can see if there is e.g. some important security update or a change that might affect something in our apps.
