Need to unpin dask, distributed in Jupyter env, climex.ipynb intermittent slow

[tlvu]

Pinned since https://github.com/Ouranosinc/PAVICS-e2e-workflow-tests/pull/101.

dask and distributed was causing PAVICStutorial_ClimateDataAnalysis-3Climate-Indicators.ipynb to run excessively slow: Finch did a similar dask and distributed pinning in https://github.com/bird-house/finch/pull/226

cf_xarray caused climex.ipynb to be intermitently slow:

See many builds in https://github.com/Ouranosinc/PAVICS-e2e-workflow-tests/pull/101 for intermittent slow climex.ipynb.

Normal: 1.5 minutes

11:09:36  pavics-sdi-master/docs/source/notebooks/WPS_example.ipynb ..........     [ 13%]
11:10:51  pavics-sdi-master/docs/source/notebooks/climex.ipynb ..........          [ 18%]

Slow: 4.5 minutes

climex.ipynb intermittent slow seems to already present since image pavics/workflow-tests:220121 (before this pinning) but much less frequent but here is one of the rare build that shows it: job-PAVICS-e2e-workflow-tests-current-production-version-1-consoleText.txt a whopping 11 minutes !

12:02:35  pavics-sdi-master/docs/source/notebooks/WPS_example.ipynb ..........     [ 13%]
12:13:15  pavics-sdi-master/docs/source/notebooks/climex.ipynb ..........          [ 18%]

Update:

• It's climex.ipynb that is intermittently slow, not WPS_example.ipynb, I was badly reading the Jenkins output

Should be fixed by https://github.com/Ouranosinc/PAVICS-e2e-workflow-tests/pull/106
