Bump all upload/download artifact GHAs to v4

Related: #414 / {#413, #415}

got an email 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.

and found few in my (forked) cri-dockerd repo

n.b.: there are some breaking changes in v4 artifact actions actions to be mindful of:

• upload-artifact
• download-artifact

Proposed Changes

• Bump all action/upload-artifact from the deprecated v3 to v4
• Bump all action/download-artifact from the deprecated v3 to v4
