ZTS: Update deprecated Github Action version numbers

GitHub Actions is transitioning from Node 16 to Node 20.

So we need to update these:
- actions/checkout@v3 -> v4
- actions/download-artifact@v3 -> v4
- actions/upload-artifact@v3 -> v4 and some minor changes

Update also the documentation of the testings workflow.

 1) build zfs modules for Ubuntu 20.04 and 22.04 (~15m)
 2) 2x zloop test (~10m) + 2x sanity test (~25m)
-3) functional testings in parts 1..5 (each ~1h)
+3) 4x functional testings in parts 1..4 (each ~1h)
 4) cleanup and create summary
    - content of summary depends on the results of the steps
