"""install.ps1's self-contained PowerShell suites, under Windows PowerShell 5.1 and pwsh 7.

``scripts/tests/*.ps1`` drive the real installer as a subprocess and exit
non-zero on any failed assertion. install.ps1 is delivered via ``irm | iex``
into whatever shell the user already has, and 5.1 is what ships with Windows,
so each suite runs under both: a construct that only parses under 7 is a broken
installer for most of the people hitting it.
