GitHub Actions: V2 artifact actions

We have released v2 versions of the upload-artifact and download-artifact actions.

The actions have been completely rewritten using typescript in contrast to the v1 versions which are plugins tied to the runner.

New features and bug fixes:

• Upload artifacts using a wildcard pattern, a directory path or an individual file path
• Upload artifacts without having to specify an artifact name
• Download all artifacts at once
• Fix issues related to artifact upload and download not working in containers
