ci: Upgrade upload-artifact action to v4 (#2376)

`upload-artifact` v3 has been deprecated for a while now and Github
Actions prevent its use now by automatically failing any job using it.

Besides upgrading to the latest major version of the action, we add a
compression level option that should better suit our needs (i.e. large
files not easily compressed).
