I noticed that the docs for pd.merge() and pd.merge_asof() were requiring the first argument to be a DataFrame, but in fact, they can be a Series. This PR updates the docs and the types to fix that issue.

Didn't think a whatsnew entry was needed, and I skipped creating an issue, but will do so if required.

I think you should use DataFrame | Series instead of FrameOrSeriesUnion. (See #40876 for more context)
