doc: fix typo on child_process.md

This note on `options.stdio` mentions that it's not recommended to pass `stdin` as a writable stream and `stdout/stderr` as readable, but then proceeds to say to always check that `stdin` is writable and `stdout/stderr` are readable. Going by the examples and the fact that `process.stdin` is readable and `process.stdout/process.stderr` are writable, I'm assuming that the types in the recommendation got swapped.
