x/website: The StderrPipe example refers to "io.ReadAll"

The StderrPipe example has an error in it. It refers to "io.ReadAll" and it should be "ioutil.ReadAll" from io/ioutil package.

io.ReadAll was added in Go 1.16 and replaced ioutil.ReadAll with the ioutil being deprecated with ioutil.ReadAll just calling io.ReadAll so the documentation should be correct for Go 1.16 and beyond. Not sure if there is a way to see documentation for older releases via the website. godoc would work locally, however.

https://golang.org/pkg/io/ioutil

As of Go 1.16, the same functionality is now provided by package io or package os, and those implementations should be preferred in new code. See the specific function documentation for details.

See https://golang.org/doc/go1.16#ioutil

Working as intended.

Ah, fair enough. I'll get my coat!
