Use smaller testdata for Raven tutorial notebook so can enable Raven notebooks on Jenkins

[tlvu]

The goal is to enable Raven tutorial notebooks on Jenkins, just like Finch and Pavics-sdi notebooks currently.

This means Raven notebooks should pass on all test deployments of PAVICS, not just on prod deployment. So we need to replicate testdata to all the test deployments.

This notebook https://github.com/Ouranosinc/raven/blob/3c768f167fbb7515206b63b90020e57708ebbc4d/docs/source/notebooks/Full_process_example_1.ipynb use two gigantic testdata file (ERA5_tas = "https://pavics.ouranos.ca/twitcher/ows/proxy/thredds/dodsC/birdhouse/ecmwf/era5_rechunk/tas_era5_reanalysis_hourly_2020.nc", ERA5_pr = "https://pavics.ouranos.ca/twitcher/ows/proxy/thredds/dodsC/birdhouse/ecmwf/era5_rechunk/pr_era5_reanalysis_hourly_2020.nc") that are 17G each !

Either:

• change for other smaller testdata
• change for .ncml link instead of .nc (.ncml do not need to be replicated to test deployments, they are taken directly on the prod server)
• change the hostname from pavics.ouranos.ca to boreas.ouranos.ca so these .nc files are taken directly from prod server instead of from the test server

@tlvu Just by curiosity, any update on this one? This would allow us to run the e2e raven tests, which are required for all the PRs regarding raven.

@huard ? I have to defer to you as I do not understand the notebook enough to be able to make the call.

I made this choice initially because the performance with the NcML was terrible. It just hanged there forever. Since the NcML is now using rechunked date, we should check if performance is acceptable.
