WIP: chore: bump gh actions to v4 because node dep

[td-famedly]

This will break your flows if you use @V3. td went ahead and bumped everything in frontend to v4 already so this is a quick hack for now.

Setting to draft/wip until someone actually invests time in this migration.

This doesn't work, each artifact needs a unique name in v4. This upload to the same name for every matrix entry.

(slashes aren't valid either, need to fix that after sleeping :))

Current state looks like it's the only way forward, I suppose we don't need to build docker images for platforms other than linux anyway.

Anything else still holding this up? The workflow has been deprecated at this point, so we should get this through.

Rebased the branch, looks fine to me, but clearly I have no permissions to do anything here at the minute ;)
