Adding notes to exceptions is a new feature in python 3.11.
Perhaps we should wait before merging this? If I understand xarray's deprecation policy correctly then 3.11 will only be the minimum supported version of python 24 months after 3.11 is released, which is 12 months from now...

you could use a helper for this:
def add_note(err: BaseException, msg: str) -> None:
# TODO: remove once python 3.10 can be dropped
if sys.version_info < (3, 11):
err.__notes__ = getattr(err, "__notes__", []) + [msg]
else:
err.add_note(msg)
…a info in the error message
