Subject: [PATCH] ci: run the Scoop installer as a script file, not through
 Invoke-Expression

ScoopInstaller/Install#136 (2026-08-27) made install.ps1 skip the install
flow when it is dot-sourced: the script now only calls Install-Scoop when
$MyInvocation.InvocationName is not '.'. GitHub Actions runs a pwsh step by
dot-sourcing the step script, so `irm get.scoop.sh | iex` inherits that
invocation name, defines the functions and exits without installing. The
next step then fails on `scoop config` within a second. Every Preview Build
and release build in this repository has failed that way on the
windows-11-arm job since 09:48 UTC.

Download the installer to a file and run it with the call operator, whose
invocation name is the file path, and fail the step if scoop.ps1 is not in
the shims directory afterwards.
