Add multipass to `App Paths` instead of `PATH`

[soredake]

What are you trying to do? PATH can become too long and installer will give you this warning:

Using App Paths instead of PATH will avoid this problem.

What's your proposed solution? Adding something like in installer (really easy): https://github.com/thonny/thonny/blob/e9b8b82f671f4cfee8c9042569706d200d26da96/packaging/windows/inno_setup.iss#L103-L108

Thanks for the suggestion @soredake.

Oops, my bad, powershell/pwsh do not use App Paths at all, they only use PATH.
