au failing to push package updates with PowerShell Core 7.3

[flcdrg]

There seems to be a breaking change between PS 7.2 and 7.3 that is causing AU to fail when trying to push new package versions.

I can see Appveyor seems to have upgraded their images from 7.2 to 7.3 a few days ago and since then all my updates are failing. eg.

[54/55] sqltoolbelt ERROR:
Chocolatey v1.3.0 File specified is either not found or not a .nupkg file. 'sqltoolbelt.2023.03.01.nupkg ' (50.30s)
[55/55] vt-cli ERROR:
Chocolatey v1.3.0 File specified is either not found or not a .nupkg file. 'vt-cli.0.12.0.nupkg ' (19.76s)

The extra trailing space does look suspicious

Spent a few hours trying to figure out what's going on, and I'm stumped. Not easy to debug as the codebase uses PowerShell Jobs, and as far as I can tell, you can't set breakpoints/step through Jobs. Also weird, I get different behaviour running in VS Code vs from PowerShell in Terminal. Very weird.

Same for me with Chocolatey 2.0

FWIW I have a branch on my fork that is working - https://github.com/flcdrg/chocolatey-au/tree/fix-warnings

And now my branch stopped working (mostly because I think GitHub Actions upgraded the version of PowerShell they use from 7.2 to 7.3)
