Update prod urls in datasets/nceo-biomass-statistics.ipynb

[anayeaye]

What

Update nceo-biomass-statistics notebook (in datasets) to use production urls.

Why

1. VEDA production is released at openveda.cloud and we want to upgrade our documentation to direct users to the more stable datastore.
2. The staging data and APIs will be persisted but the urls will be moved to staging.openveda.cloud/api/stac and staging.openveda.cloud/api/raster.

Ran nceo-biomass-statistics via JupyterHub and it seems the default kernel settings aren't sufficient to run the notebook and it will result in an error that the kernel has restarted. Running the notebook locally on my machine doesn't create the same issue. I can't pick up on this task this sprint but if anyone else can, I hope my notes above are somewhat helpful!

I did find that changing the approach resulted in a much smaller memory footprint #149
