I’m sure I am doing something silly, but neither mypy nor pyright recognise that `io.text_encoding()` exists. Any pointers?

```console
% python -c "import io; io.text_encoding(None)"
% mypy -c "import io; io.text_encoding(None)"  
<string>:1: error: Module has no attribute "text_encoding" [attr-defined]
Found 1 error in 1 file (checked 1 source file)

```
