Test PowerShell Preview in CI

Replaces #1439.

Funny day year to test this, the daily isn't available.

So apparently the Daily build hasn't existed in a year. I opened PowerShell/PowerShell#25124 to correct the install script, and I don't expect this to pass until it's merged as I updated it to install the preview to ~/.powershell-preview (like the Daily was) which makes way more sense.

Lol. But given that there are now multiple supported PowerShell versions available (LTS and current), the more valuable thing is maybe to test with those versions and the latest preview. Also, daily probably adds a bit of noise.

Ah I didn't update the title. This will test the PowerShell Preview, I'm just waiting on my upstream PR to be merged so I don't have to install it to a -Destination manually.

LGTM!

Gotcha. Makes sense. But I think it would also be useful to additionally also have one run with PowerShell 7.4 since it is LTS but the CI runners always use the latest version, which is 7.5 atm. For now we could just run test suite with PS 7.4 locally, just requires manual uninstall of newer versions because some tests call into pwsh from PATH
