Node 16 Deprecation Warning

[christian-ci]

Describe the bug
The GitHub Actions workflow is generating a deprecation warning due to the use of Node.js 16. GitHub Actions now requires the use of Node.js 20, as Node.js 16 actions have been deprecated.

To Reproduce
Steps to reproduce the behavior:

1. Go to the GitHub repository containing the workflow.
2. Run the GitHub Actions workflow.
3. Observe the deprecation warning in the workflow logs.
4. The warning specifically mentions the use of Node.js 16 in aws-actions/amazon-ecr-login@v1.

Expected behavior
The expected behavior is for the GitHub Actions workflow to run without any deprecation warnings. It should use the updated Node.js 20 environment for all actions.

It looks like this was already fixed in #532, you just need to use v2.
