Thanks for reaching out and the proactive contribution. Though I think this is not actually a typo. I am inclined to close this, but maybe there is more detail we could add that explains what's going on here. Thoughts?

This isn't actually a typo. Acero is the name of the streaming C++ query engine that the Arrow R package uses. See https://arrow.apache.org/docs/cpp/acero.html

We do mention this for example here: https://arrow.apache.org/docs/r/reference/acero.html?q=acero#null which is also above this at https://github.com/apache/arrow/pull/48840/changes#diff-8e2b0f2944713c80b312477fd9e90bf65071251dd380b84940127cc167c7b55aR27-R28
