cabal list-bin doesn't suppress stdout from other phases

[hasufell]

Describe the bug

cabal list-bin doesn't suppress stdout from internal cabal phases, leading to broken behavior when you want to save the result in a variable.

To Reproduce

1. git clone [email protected]:hasufell/list-bin.git
2. cd list-bin
3. cabal build
4. foo=$(cabal list-bin exe:list-bin)
5. ${foo}

Resulting in:

bash: Downloading: command not found

Expected behavior

The only thing sent to stdout is the binary location.

System information

• Operating system: Fedora 39
• cabal: 3.10.3.0

This seems like a long-standing issue in multiple cabal commands. Perhaps we should take inspiration from other project build tools and try to come up with a fix once and for all? E.g., cargo seems to printing everything to stderr (rustc errors, progress notifications, etc...).

A disadvantage of sending all output to stderr is that we probably break someone's scripts.
