docs: broken link at https://xarray.pydata.org/en/stable/user-guide/terminology.html

[phil-blain]

What happened?

The link to https://www.unidata.ucar.edu/software/netcdf/docs/netcdf_data_set_components.html#variables in the "Variables" heading is broken, I think it should now link to the NetCDF user guide: https://docs.unidata.ucar.edu/nug/current/netcdf_data_set_components.html#variables

What did you expect to happen?

Link works

Minimal Complete Verifiable Example

1. Click on the  "NetCDF-like variable" link on page https://xarray.pydata.org/en/stable/user-guide/terminology.html. 
2. 404

MVCE confirmation

• Minimal example — the example is as focused as reasonably possible to demonstrate the underlying issue in xarray.
• Complete example — the example is self-contained, including all data and the text of any traceback.
• Verifiable example — the example copy & pastes into an IPython prompt or Binder notebook, returning the result.
• New issue — a search of GitHub Issues suggests this is not a duplicate.

Thanks @phil-blain This should be a really easy fix if you're up for contributing: See https://github.com/pydata/xarray/blob/main/doc/user-guide/terminology.rst for the source and https://docs.xarray.dev/en/stable/contributing.html#contributing-to-the-documentation for instructions

Yeah, I just wanted to confirm this was indeed the intended link target:)

Closing, I forgot the "Closes" trailer when I authored my commit and PR.
