Add dependencies for Callum Rollo's tutorial and adjust the default environment to include them.

Removing the test dependencies from last year, and update Pangeo Notebook to 2024.08.07

@callumrollo this should add your dependencies. If you want you can pull down the repo and run them yourself, or you can wait till we land the image on the hub and give it a shot.

I ran pixi add -f 24-Callum numpy cartopy pandas gsw matplotlib seaborn cmocean cmcrameri tqdm seaborn argopy ipyleaflet searvey shapely cftime ioos_qc cf_xarray to add Callum's dependencies from https://oceanhackweek.slack.com/archives/C07GNPX1D35/p1723540737149639 then tweaked pixi.toml's environment table to include his feature, and pixi install to update the lockfile.
