Describe the feature

Currently, Zed uses powershell as the default shell on Windows. It would be nice if Zed defaulted to using pwsh if detected on the user's system.

Background

On Windows, Windows PowerShell (aka powershell.exe (versions 1-5.1) is bundled as the system shell.
In 2019, Microsoft released pwsh 7 as an OSS and cross-platform re-implementation and modern replacement for powershell 5.1.
pwsh, however, is NOT bundled with Windows and is actually what the update nag message that shows up everytime you launch powershell is referring to.

Environment

Version: Zed 0.165.4 @ c8199d4
Source: MSYS2 (UCRT64)
OS: Windows 11, 23H2

The new PowerShell is vastly superior, and Zed should consider preferring it when available, especially given that there is no equivalent to chsh for defining a user's preferred Shell like there is on macOS/Linux/etc.

I think I may have a try on that

I was using the option in the config to set the terminal program, but this would be much smoother as finding the specific apps in the microsoft store is a pain, and looks like:

"terminal": {
    "shell": {
        "program": "C:\\Users\\<username>\\AppData\\Local\\Microsoft\\WindowsApps\\Microsoft.PowerShell_8wekyb3d8bbwe\\pwsh.exe"
    }
},

which would be a great thing to just "detect" since the default is pwsh 1.0 and we are on 7.5.something at this stage, also, I should note that as of updating from nightly a month ago(ish) and last night, adding this to the settings.json causes a fun panic on launch
