Link needed for "Working with labeled data" tutorial

[tylere]

The section on Data Structures refers to a tutorial:

"... see the Working with labeled data tutorial"

but no link is provided and it is not clear what tutorial it is referring to.

Thanks for pointing this out. The missing link is referring to the next subchapter in that section https://tutorial.xarray.dev/fundamentals/01.1_creating_data_structures.html

PR's welcome!
