Subject: [PATCH] csv: Make _Writer.write positional-only (#6475)

At runtime it only uses positional parameters.

I think this works fortuitously in mypy and pyright because mypy ignores parameter names in protocols and pyright has a bug that allows passing positional-only to pos-or-keyword params (microsoft/pyright#2652) and the parameter to `io.TextIO.write` happens to be `__s`.
