Split testing job into several

This patch separates the Test job of the PR workflow into several smaller jobs: 1) create a testing sandbox and deploy Talos, 2) install Cozystack and configure it, 3) install managed applications and run e2e tests. This lets developers shorten the feedback loop if tests are merely acting flaky and aren't really broken. It's not the right way, but it's 80/20. Signed-off-by: Timofei Larkin <lllamnyp@gmail.com>
