Changed Spining to clockwise for jupyter lab build

[adityar-r]

References

This request address this issue: #7169

Code changes

As mentioned in the issue, the line at jupyterlab/jupyterlab/commands.py
is changed from
spinner = itertools.cycle(['-', '/', '|', '\\'])
to
spinner = itertools.cycle(['-', '\\', '|', '/'])
This helps in displaying a clockwise animation during the issue of jupyter lab build command.
