Use image's Powershell Core for Windows tests
What does this MR do?
It removes a hack in TestDockerServiceHealthcheck
that copied pwsh to a powershell executable.
Why was this MR needed?
Because the reason for the hack no longer exists (PowerShell Core shell was not yet fully supported (#13139 (closed))).
What's the best way to test this MR?
The TestDockerServiceHealthcheck
should be able to execute powershell
.
What are the relevant issue numbers?
Closes #28031 (closed)
