Expose a html repr for all datasets somewhere?

[jbusecke]

I just took way to long to cycle through all datasets in order to find a dataset that fits my requirements. I think it would be super useful to have a small gallery/page that just shows the html repr for all datasets (automatically updated by CI). This could be integrated into the tutorial loading/opening functionsdocstrings.

Where would the best location for this be?

Happy to look into this when time is available.

Simple idea of what I am suggesting here:

import xarray as xr
ds_names = ["air_temperature", "air_temperature_gradient", "basin_mask","rasm","ROMS_example", "tiny", "era5-2mt-2019-03-uk.grib", "eraint_uvz", "ersstv5"]

for name in ds_names:
    ds = xr.tutorial.open_dataset(name)
    display(ds) # write this out with a name

Yes good idea! We could even have some API like xr.tutorial.list_datasets() and/or xr.tutorial.describe_datasets(). For the latter adding a small description besides each repr would be nice too.
