Probe Microsoft.PowerShell.Archive in getModule E2E test

Merging #2328 un-skipped the Windows PowerShell E2E suite, which surfaced
a pre-existing host gap in `CanSendGetModuleRequestAsync`: it probed
`Microsoft.PowerShell.Management`, but Windows PowerShell's in-box core
modules are snap-in based and are not returned by
`Get-Module -ListAvailable`. The handler correctly resolved nothing, so
`Assert.NotNull` failed on the Windows PowerShell leg while passing on
PowerShell 7 (where the core modules ship as files).

Probe `Microsoft.PowerShell.Archive` instead: it is a file-based module
present in the module path on both Windows PowerShell and PowerShell 7+,
so the test exercises the handler on every host without skipping or
loosening any assertion.
