BUG: Stable docs intersphinx has a duplicate std:term:y #29337
Description
When building with intersphinx we get a warning which you can replicate with intersphinx directly
$ python -m sphinx.ext.intersphinx https://scikit-learn.org/stable/objects.inv | grep " y "
WARNING:sphinx.sphinx.util.inventory:inventory <> contains multiple definitions for std:term:y
y : glossary.html#term-y
Only one term shows up in the grep presumably because intersphinx chooses one of the two, but the WARNING line actually shows up in doc builds.
