Port tutorial notebooks to use Beam

[derekocallaghan]

This PR will be used to port tutorial notebooks to beam-refactor:

The first is an initial port of the NetCDF Zarr Multi-Variable Sequential Recipe: NOAA World Ocean Atlas notebook to use the beam-refactor approach:

• A custom transform is provided, containing the preprocessor function logic in the non-Beam notebook version. I've included some links to Beam documentation here but this could be expanded if required.
• The recipe approach is similar to that described in intro_tutorial_part2
  • It currently creates and specifies a target_path to StoreToZarr. See [Beam-Refactor] Edits to intro_tutorial_part[*] #485 for discussion on this point as it may be subject to change.
• I've run it locally and rebuilt the docs, it seems to work without problems. The only issue I spotted was the final plot range is different to the non-Beam version, but I couldn't see what the problem was and I don't think it's related to Beam usage.
• Although it contains references to the Xarray-to-Zarr Sequential Recipe: NOAA OISST notebook, I haven't ported this yet as it contains functionality which may no longer be provided by the beam-refactor branch. I'm going to look at this next. In the meantime, this current notebook may be useful as an example for porting other tutorial notebooks (@norlandrhagen).

Partly fixes #483

I'm going to use this PR for any tutorial notebooks that I port rather than a single PR per notebook. It probably makes more sense to review them together.

Hi @cisaacstern, this PR is ready for review now, involving porting three of the original notebooks, with one excluded. I removed references to XarrayZarrRecipe etc in the tutorial index page. The ported notebooks are available at https://pangeo-forge--487.org.readthedocs.build/en/487/pangeo_forge_recipes/tutorials/index.html

The HDF Reference Recipe for CMIP6 notebook hasn't been ported yet as I assume it's dependent on #486. @norlandrhagen is this okay with you?

The TerraClimate notebook port is covered by #490.

I'll create separate PRs for the remaining tasklist in #483.

Hi @cisaacstern, if the notebook changes are okay with you, it might be easier to merge this before merging the latest store_name PR from @yuvipanda (#495). I can update the notebooks afterwards to include the required store_name in each StoreToZarr usage.

Hi @rabernat and @cisaacstern, if you're free, can you take a look at these notebook changes? If you're happy with them, I'll work on the remaining documentation tasks in #483. Thanks.

@derekocallaghan these look great to me! The illustrations of how to add preprocessors are very clear, and helped me understand how easy that is do with beam-refactor. Thanks so much, good to merge IMO!

Psyched to see this PR land! Thanks @derekocallaghan!
