`Just`’s `ignoreOutPut` overload.

just_ignore_output_specialization.swift
Just("someString")
.ignoreOutput() /// (1) Combine specializes
/// [`Just`’s overload of `ignoreOutput`](https://developer.apple.com/documentation/combine/just/3343929-ignoreoutput)
/// to return an `Empty<String, Never>` (note, the output type didn’t get `Never`’d out) instead of wrapping
/// it a [`Publishers.IgnoreOutput`](https://developer.apple.com/documentation/combine/publishers/ignoreoutput) level.
.append("anotherStringPostFinished") /// (2) Since upstream is an `Empty<String, Never>` and the
/// `Output` generic _didn’t_ get `Never`’d out, the `append` here can carry on accepting `String`s.
