`cargo +nightly doc` compilation broken

Description
We're currently running into an issue trying to test our documentation build: https://github.com/informalsystems/tendermint-rs/pull/910/checks?check_run_id=2878946357

It appears as though it's due to the new named pipe code introduced in #3760, specifically the code in tokio/src/net/windows/named_pipe.rs

The command to run to reproduce this problem locally on our side (from Ubuntu) is:

RUSTFLAGS="--cfg docsrs" cargo +nightly doc --all-features

The correct command is:

RUSTDOCFLAGS="--cfg docsrs" cargo +nightly doc --all-features

Excellent, thanks @Darksonn! That fixed it.
