Update workflows to use v4 of the artifact actions

[anfredette]

From GitHub:

Artifact actions v3 will be closing down by January 30, 2025. You are receiving this email because you have GitHub Actions workflows using v3 of actions/upload-artifact or actions/download-artifact. After this date using v3 of these actions will result in a workflow failure. Artifacts within their retention period will remain accessible from the UI or REST API regardless of the version used to upload.

To raise awareness of the upcoming removal, we will temporarily fail jobs using v3 of actions/upload-artifact or actions/download-artifact. Builds that are scheduled to run during the brownout periods will fail. The brownouts are scheduled for the following dates and times:

January 9th, 12pm - 1pm EST
January 16th, 10am-2pm EST
January 23rd, 9am-5pm EST

What you need to do

Update workflows to begin using v4 of the artifact actions as soon as possible. While v4 improves upload and download speeds by up to 98% and includes several new features, there are key differences from previous versions that may require updates to your workflows. Please see the documentation in the project repositories for guidance on how to migrate your workflows.
