*DRAFT** ci: Revert linux deploy changes

[tippmar-nr]

• Reverts the changes made in ci: Update linux deploy to run debian:stable #2113, as we discovered that there is some sort of conflict with the aws cli when running on debian:stable in a container on a Github runner.
• Modifies the deploy_agent workflow so that it checks out the repo and uses the files in the deploy folder rather than downloading those files from the build artifact uploaded from the all_solutions workflow. This was necessary to allow for testing changes to the linux deploy Dockerfile and scripts.
• Removes the deploy folder from deploy-artifacts in the all_solutions workflow.
• Attempts (yet again) to fix a bug in the post_deploy_agent workflow where we want the workflow to delay 5 minutes when called from another workflow but not when invoked manually.
• Removes the (unnecessary) get-external-artifacts job from the publish_release_notes workflow and refactors the primary job to download the artifacts instead.
