Description of the new feature/enhancement

Please let me configure the audible bell so that it plays a sound other than "Critical Stop". I'd like to select a sound with a shorter duration and perhaps lower volume.

This request is for Windows Terminal, not the console host.

Proposed technical implementation details (optional)

Ever since #7679, the implementation of the audible bell hardcodes SND_ALIAS_SYSTEMHAND:

I can think of two ways to make this configurable:

• Let me specify the path of a sound file in settings.json. I think this should be configurable per profile, like the bellStyle setting (Feature Request: disable bell #2360) is.

• Alternatively, register Windows Terminal with the "Change system sounds" feature in Control Panel so that I can choose a sound there. According to C++ at Work: Web Version Checking, Adding Sound to an App, this involves the HKEY_CURRENT_USER\AppEvents\Schemes\Apps Registry key and the SND_APPLICATION flag. I suspect that the MSIX packaging of Windows Terminal won't allow writing to such Registry keys, though.
