Update tests pipeline

[fedem-p]

Updated some github actions

One test unfortunately leaves python hanging silently.
It seems to be a problem related to the .join function that doesn't have a timeout.

here's the stack trace:

Traceback (most recent call last):
  File "c:\users\feder\miniconda3\envs\napari-env\lib\multiprocessing\util.py", line 357, in _exit_function
    p.join()
  File "c:\users\feder\miniconda3\envs\napari-env\lib\multiprocessing\process.py", line 149, in join
    res = self._popen.wait(timeout)
  File "c:\users\feder\miniconda3\envs\napari-env\lib\multiprocessing\popen_spawn_win32.py", line 108, in wait
    res = _winapi.WaitForSingleObject(int(self._handle), msecs)```
