There's a reference in datasets.rst that no longer points to anything after #29104 was merged:

I don't understand why it wasn't caught by the CI in #29104. I saw it in the 1.5.1 release branch (#29382), see https://output.circle-artifacts.com/output/job/b0d90a86-a5d1-4ac2-b9b5-c3e6397555da/artifacts/0/doc/_changed.html.

I will ignore it for the release, but we need to rephrase this paragraph because it references a part of the doc that no longer exists.
