Subject: [PATCH] Propagate te.exe exit code from run-tests.ps1

`te.exe` is invoked as a native command, so its failure should be
detected via `0` rather than `!True` (which can be
unreliable for native processes under `Set-StrictMode`). Also
propagate the actual exit code instead of substituting a hardcoded `1`
so callers (CI, wrapper scripts) can distinguish between te.exe failure
modes.

Also fix the `-Package` parameter doc: the actual default is
`.\installer.msix`, not `.\wsl.msix`.
