Backport PR #40768: DOC/CI: temp pin of decorator (IPython dependency)
this doesn't need to be backported, as it's already reverted on master see https://github.com/pandas-dev/pandas/pull/40801#issuecomment-814224625 although not sure if this will fix. currently recreating this env locally That are different warnings than addressed in this PR. Comparing the two envs, another difference is the docutils version. They had a new release a few days ago, and since that broke a bunch of stuff in sphinx, I pinned the docutils version in the pydata-sphinx-theme. But the 1.2.x branch is still using an older version of the theme (not having this pin), so it might be https://github.com/pandas-dev/pandas/pull/40407 we need to backport. Thanks @jorisvandenbossche . yes this doesn't fix. will try  #40407 instead.
