(consult-omni-apps) Apps cannot write to stderr after launching

[Dev380]

Describe the bug

Some apps (I tested using armcord, which uses electron) expect stderr to be open after launching. However, consult-omni currently keeps it closed, resulting in an error with these apps.

To Reproduce Steps to reproduce the behavior:

1. Open consult-omni-apps
2. Launch armcord, discord or similar electron app
3. See error

Expected behavior

The app should launch normally as would be expected when using gtk-launch appname.desktop from a terminal.

Screenshots

Important Information:

• OS: Arch Linux
• Emacs 30.0.50
• Version of consult: 1.7
• Installation: doom emacs's straight.el with standard configuration.
• If there is an error message: N/A

This was resolved in #24, so closing it now!
